That the {e} generation to come might know them, even the children which should be born; who should arise and declare them to their children:

(e) He shows how the children would be like their father's: that is, in maintaining God's pure religion.

Matthew Henry's Concise Commentary

78:1-8 These are called dark and deep sayings, because they are carefully to be looked into. The law of God was given with a particular charge to teach it diligently to their children, that the church may abide for ever. Also, that the providences of God, both in mercy and in judgment, might encourage them to conform to the will of God. The works of God much strengthen our resolution to keep his commandments. Hypocrisy is the high road to apostacy; those that do not set their hearts right, will not be stedfast with God. Many parents, by negligence and wickedness, become murderers of their children. But young persons, though they are bound to submit in all things lawful, must not obey sinful orders, or copy sinful examples.

Matthew Henry's Whole Bible Commentary

PSALM 78

This psalm is historical; it is a narrative of the great mercies God had bestowed upon Israel, the great sins wherewith they had provoked him, and the many tokens of his displeasure they had been under for their sins. The psalmist began, in the foregoing psalm, to relate God's wonders of old, for his own encouragement in a difficult time; there he broke off abruptly, but here resumes the subject, for the edification of the church, and enlarges much upon it, showing not only how good God had been to them, which was an earnest of further finishing mercy, but how basely they had conducted themselves towards God, which justified him in correcting them as he did at this time, and forbade all complaints. Here is, I. The preface to this church history, commanding the attention of the present age to it and recommending it to the study of the generations to come (v. 1-8). II. The history itself from Moses to David; it is put into a psalm or song that it might be the better remembered and transmitted to posterity, and that the singing of it might affect them with the things here related, more than they would be with a bare narrative of them. The general scope of this psalm we have (v. 9-11) where notice is taken of the present rebukes they were under (v. 9), the sin which brought them under those rebukes (v. 10), and the mercies of God to them formerly, which aggravated that sin (v. 11). As to the particulars, we are here told, 1. What wonderful works God had wrought for them in bringing them out of Egypt (v. 12-16), providing for them in the wilderness (v. 23-29), plaguing and ruining their enemies (v. 43-53), and at length putting them in possession of the land of promise (v. 54, 55). 2. How ungrateful they were to God for his favours to them and how many and great provocations they were guilty of. How they murmured against God and distrusted him (v. 17-20), and did but counterfeit repentance and submission when he punished them (v. 34-37), thus grieving and tempting him (v. 40-42). How they affronted God with their idolatries after they came to Canaan (v. 56-58). 3. How God had justly punished them for their sins (v. 21, 22) in the wilderness, making their sin their punishment (v. 29-33), and now, of late, when the ark was taken by the Philistines (v. 59-64). 4. How graciously God had spared them and returned in mercy to them, notwithstanding their provocations. He had forgiven them formerly (v. 38, 39), and now, of late, had removed the judgments they had brought upon themselves, and brought them under a happy establishment both in church and state (v. 65-72). As the general scope of this psalm may be of use to us in the singing of it, to put us upon recollecting what God has done for us and for his church formerly, and what we have done against him, so the particulars also may be of use to us, for warning against those sins of unbelief and ingratitude which Israel of old was notoriously guilty of, and the record of which was preserved for our learning. "These things happened unto them for ensamples," 1 Co. 10:11; Heb. 4:11.

Maschil of Asaph.

Verses 1-8

These verses, which contain the preface to this history, show that the psalm answers the title; it is indeed Maschil-a psalm to give instruction; if we receive not the instruction it gives, it is our own fault. Here,

I. The psalmist demands attention to what he wrote (v. 1): Give ear, O my people! to my law. Some make these the psalmist's words. David, as a king, or Asaph, in his name, as his secretary of state, or scribe to the sweet singer of Israel, here calls upon the people, as his people committed to his charge, to give ear to his law. He calls his instructions his law or edict; such was their commanding force in themselves. Every good truth, received in the light and love of it, will have the power of a law upon the conscience; yet that was not all: David was a king, and he would interpose his royal power for the edification of his people. If God, by his grace, make great men good men, they will be capable of doing more good than others, because their word will be a law to all about them, who must therefore give ear and hearken; for to what purpose is divine revelation brought our ears if we will not incline our ears to it, both humble ourselves and engage ourselves to hear it and heed it? Or the psalmist, being a prophet, speaks as God's mouth, and so calls them his people, and demands subjection to what was said as to a law. Let him that has an ear thus hear what the Spirit saith unto the churches, Rev. 2:7.

II. Several reasons are given why we should diligently attend to that which is here related. 1. The things here discoursed of are weighty, and deserve consideration, strange, and need it (v. 2): I will open my mouth in a parable, in that which is sublime and uncommon, but very excellent and well worthy your attention; I will utter dark sayings, which challenge your most serious regards as much as the enigmas with which the eastern princes and learned men used to try one another. These are called dark sayings, not because they are hard to be understood, but because they are greatly to be admired and carefully to be looked into. This is said to be fulfilled in the parables which our Saviour put forth (Mt. 13:35), which were (as this) representations of the state of the kingdom of God among men. 2. They are the monuments of antiquity-dark sayings of old which our fathers have told us, v. 3. They are things of undoubted certainty; we have heard them and known them, and there is no room left to question the truth of them. The gospel of Luke is called a declaration of those things which are most surely believed among us (Lu. 1:1), so were the things here related. The honour we owe to our parents and ancestors obliges us to attend to that which our fathers have told us, and, as far as it appears to be true and good, to receive it with so much the more reverence and regard. 3. They are to be transmitted to posterity, and it lies as a charge upon us carefully to hand them down (v. 4); because our fathers told them to us we will not hide them from their children. Our children are called theirs, for they were in care for their seed's seed, and looked upon them as theirs; and, in teaching our children the knowledge of God, we repay to our parents some of that debt we owe to them for teaching us. Nay, if we have no children of our own, we must declare the things of God to their children, the children of others. Our care must be for posterity in general, and not only for our own posterity; and for the generation to come hereafter, the children that shall be born, as well as for the generation that is next rising up and the children that are born. That which we are to transmit to our children is not only the knowledge of languages, arts and sciences, liberty and property, but especially the praises of the Lord, and his strength appearing in the wonderful works he has done. Our great care must be to lodge our religion, that great deposit, pure and entire in the hands of those that succeed us. There are two things the full and clear knowledge of which we must preserve the entail of to our heirs:-(1.) The law of God; for this was given with a particular charge to teach it diligently to their children (v. 5): He established a testimony or covenant, and enacted a law, in Jacob and Israel, gave them precepts and promises, which he commanded them to make known to their children, Deu. 6:7, 20. The church of God, as the historian says of the Roman commonwealth, was not to be res unius aetatis-a thing of one age but was to be kept up from one generation to another; and therefore, as God provided for a succession of ministers in the tribe of Levi and the house of Aaron, so he appointed that parents should train up their children in the knowledge of his law: and, when they had grown up, they must arise and declare them to their children (v. 6), that, as one generation of God's servants and worshippers passes away, another generation may come, and the church, as the earth, may abide for ever; and thus God's name among men may be as the days of heaven. (2.) The providences of God concerning them, both in mercy and in judgment. The former seem to be mentioned for the sake of this; since God gave order that his laws should be made known to posterity, it is requisite that with them his works also should be made known, the fulfilling of the promises made to the obedient and the threatenings denounced against the disobedient. Let these be told to our children and our children's children, [1.] That they may take encouragement to conform to the will of God (v. 7): that, not forgetting the works of God wrought in former days, they might set their hope in God and keep his commandments, might make his command their rule and his covenant their stay. Those only may with confidence hope for God's salvation that make conscience of doing his commandments. The works of God, duly considered, will very much strengthen our resolution both to set our hope in him and to keep his commandments, for he is able to bear us out in both. [2.] That they may take warning not to conform to the example of their fathers (v. 8): That they might not be as their fathers, a stubborn and rebellious generation. See here, First, What was the character of their fathers. Though they were the seed of Abraham, taken into covenant with God, and, for aught we know, the only professing people he had then in the world, yet they were stubborn and rebellious, and walked contrary to God, in direct opposition to his will. They did indeed profess relation to him, but they did not set their hearts aright; they were not cordial in their engagements to God, nor inward with him in their worship of him, and therefore their spirit was not stedfast with him, but upon every occasion they flew off from him. Note, Hypocrisy is the high road to apostasy. Those that do not set their hearts aright will not be stedfast with God, but play fat and loose. Secondly, What was a charge to the children: That they be not as their fathers. Note, Those that have descended from wicked and ungodly ancestors, if they will but consider the word and works of God, will see reason enough not to tread in their steps. It will be no excuse for a vain conversation that it was received by tradition from our fathers (1 Pt. 1:18); for what we know of them that was evil must be an admonition to us, that we dread that which was so pernicious to them as we would shun those courses which they took that were ruinous to their health or estates.
