And Jehoiada made a {p} covenant between the LORD and the king and the people, that they should be the LORD'S people; between the {q} king also and the people.

(p) That both the king and the people should maintain the true worship of God and destroy all idolatry.

(q) That he should govern and they obey in the fear of God.

Wesley's Notes

11:17 A covenant - A sacred covenant whereby he solemnly engaged both the king, and people, that they should be the Lord's people; that they should renounce, and root out all idolatry, and set up and maintain God's true worship. Between the king - This was a civil covenant, whereby the king engaged himself to rule them justly, and in the fear of God; and the people obliged themselves to defend and obey him.

Jamieson-Fausset-Brown Bible Commentary

2Ki 11:17-20. Jehoiada Restores God's Worship.

17, 18. a covenant between the Lord and the king and the people-The covenant with the Lord was a renewal of the national covenant with Israel (Ex 19:1-24:18; "to be unto him a people of inheritance," De 4:6; 27:9). The covenant between the king and the people was the consequence of this, and by it the king bound himself to rule according to the divine law, while the people engaged to submit, to give him allegiance as the Lord's anointed. The immediate fruit of this renewal of the covenant was the destruction of the temple and the slaughter of the priests of Baal (see 2Ki 10:27); the restoration of the pure worship of God in all its ancient integrity; and the establishment of the young king on the hereditary throne of Judah [2Ki 11:19].

Matthew Henry's Concise Commentary

11:17-21 King and people would cleave most firmly to each other, when both had joined themselves to the Lord. It is well with a people, when all the changes that pass over them help to revive, strengthen, and advance the interests of religion among them. Covenants are of use, both to remind us of, and bind us to, the duties already binding on us. They immediately abolished idolatry; and, pursuant to the covenant with one another, they expressed mutual readiness to help each other. The people rejoiced, and Jerusalem was quiet. The way for people to be joyful and at peace, is to engage fully in the service of God; for the voice of joy and thanksgiving is in the dwellings of the righteous, but there is no peace for the wicked.

Matthew Henry's Whole Bible Commentary

Verses 17-21

Jehoiada had now got over the harlot part of his work, when, by the death of Athaliah, the young prince had his way to the throne cleared of all opposition. He had now to improve his advantages for the perfecting of the revolution and the settling of the government. Two things we have an account of here:-

I. The good foundations he laid, by an original contract, v. 17. Now that prince and people were together in God's house, as it should seem before they stirred, Jehoiada took care that they should jointly covenant with God, and mutually covenant with each other, that they might rightly understand their duty both to God and to one another, and be firmly bound to it. 1. He endeavoured to settle and secure the interests of religion among them, by a covenant between them and God. King and people would then cleave most firmly to each other when both had joined themselves to the Lord. God had already, on his part, promised to be their God (Jehoiada could show them that in the book of the testimony); now the king and people on their part must covenant and agree that they will be the Lord's people: in this covenant, the king stands upon the same level with his subjects and is as much bound as any of them to serve the Lord. By this engagement they renounced Baal, whom many of them had worshipped, and resigned themselves to God's government. It is well with a people when all the changes that pass over them help to revive, strengthen, and advance the interests of religion among them. And those are likely to prosper who set out in the world under fresh and sensible obligations to God and their duty. By our bonds to God the bonds of every relation are strengthened. They first gave themselves to the Lord, and then to us, 2 Co. 8:5. 2. He then settled both the coronation-oath and the oath of allegiance, the pacta conventa-covenant, between the king and the people, by which the king was obliged to govern according to law and to protect his subjects, and they were obliged, while he did so, to obey him and to bear faith and true allegiance to him. Covenants are of use both to remind us of and to bind us to those duties which are already binding on us. It is good, in all relations, for the parties to understand one another fully, particularly in that between prince and subject, that the one may understand the limits of his power and prerogative, the other those of his liberty and property; and never may the ancient landmarks which our fathers have set before them be removed.

II. The good beginnings he raised on those foundations. 1. Pursuant to their covenant with God they immediately abolished idolatry, which the preceding kings, in compliance with the house of Ahab, had introduced (v. 18): All the people of the land, the mob, got together, to show their zeal against idolatry; and every one, now that they were so well headed, would lend a hand to pull down Baal's temple, his altars, and his images. All his worshippers, it should seem, deserted him; only his priest Mattan stuck to his altar. Though all men forsook Baal, he would not, and there he was slain, the best sacrifice that ever was offered upon that altar. Having destroyed Baal's temple, they appointed officers over the house of God, to see that the service of God was regularly performed by the proper persons, in due time, and according to the institutional manner. 2. Pursuant to their covenant with one another they expressed a mutual readiness to and satisfaction in each other. (1.) The king was brought in state to the royal palace, and sat there on the throne of judgment, the thrones of the house of David (v. 19), ready to receive petitions and appeals, which he would refer it to Jehoiada to give answers to and to give judgment upon. (2.) The people rejoiced, and Jerusalem was in quiet (v. 20), and Josephus says they kept a feast of joy many days, making good Solomon's observation (Prov. 11:10), When it goes well with the righteous the city rejoices, and when the wicked perish there is shouting.
