And he did that which was right in the sight of the LORD, and walked in the ways of {a} David his father, and declined neither to the right hand, nor to the left.

(a) He followed David in all points that he followed the Lord.

Matthew Henry's Concise Commentary

34:1-33 Josiah's good reign in Judah. - As the years of infancy cannot be useful to our fellow-creatures, our earliest youth should be dedicated to God, that we may not waste any of the remaining short space of life. Happy and wise are those who seek the Lord and prepare for usefulness at an early age, when others are pursuing sinful pleasures, contracting bad habits, and forming ruinous connexions. Who can express the anguish prevented by early piety, and its blessed effects? Diligent self-examination and watchfulness will convince us of the deceitfulness and wickedness of our own hearts, and the sinfulness of our lives. We are here encouraged to humble ourselves before God, and to seek unto him, as Josiah did. And believers are here taught, not to fear death, but to welcome it, when it takes them away from the evil to come. Nothing hastens the ruin of a people, nor ripens them for it, more than their disregard of the attempts made for their reformation. Be not deceived, God is not mocked. The current and tide of affections only turns at the command of Him who raises up those that are dead in trespasses and sins. We behold peculiar loveliness, in the grace the Lord bestows on those, who in tender years seek to know and to love the Saviour. Hath Jesus, the Day-spring from on high, visited you? Can you trace your knowledge of this light and life of man, like Josiah, from your youth? Oh the unspeakable happiness of becoming acquainted with Jesus from our earliest years!

Matthew Henry's Whole Bible Commentary

Chapter 34

Before we see Judah and Jerusalem ruined we shall yet see some glorious years, while good Josiah sits at the helm. By his pious endeavours for reformation God tried them yet once more; if they had known in this their day, the day of their visitation, the things that belonged to their peace and improved them, their ruin might have been prevented. But after this reign they were hidden from their eyes, and the next reigns brought an utter desolation upon them. In this chapter we have, I. A general account of Josiah's character (v. 1, 2). II. His zeal to root out idolatry (v. 3-7). III. His care to repair the temple (v. 8-13). IV. The finding of the book of the law and the good use made of it (v. 14-28). V. The public reading of the law to the people and their renewing their covenant with God thereupon (v. 29-33). Much of this we had 2 Ki. 22.

Verses 1-7

Concerning Josiah we are here told, 1. That he came to the crown when he was very young, only eight years old (yet his infancy did not debar him from his right), and he reigned thirty-one years (v. 1), a considerable time. I fear, however, that in the beginning of his reign things went much as they had done in his father's time, because, being a child, he must have left the management of them to others; so that it was not till his twelfth year, which goes far in the number of his years, that the reformation began, v. 3. He could not, as Hezekiah did, fall about it immediately. 2. That he reigned very well (v. 2), approved himself to God, trod in the steps of David, and did not decline either to the right hand of to the left: for there are errors on both hands. 3. That while he was young, about sixteen years old, he began to seek after God, v. 3. We have reason to think he had not so good an education as Manasseh had (it is well if those about him did not endeavour to corrupt and debauch him); yet he thus sought God when he was young. It is the duty and interest of young people, and will particularly be the honour of young gentlemen, as soon as they come to years of understanding, to begin to seek God; for those that seek him early shall find him. 4. That in the twelfth year of his reign, when it is probable he took the administration of the government entirely into his own hands, he began to purge his kingdom from the remains of idolatry; he destroyed the high places, groves, images, altars, all the utensils of idolatry, v. 3, 4. He not only cast them out as Manasseh did, but broke them to pieces, and made dust of them. This destruction of idolatry is here said to be in his twelfth year, but it was said (2 Ki. 23:23) to be in his eighteenth year. Something was probably done towards it in his twelfth year; then he began to purge out idolatry, but that good work met with opposition, so that it was not thoroughly done till they had found the book of the law six years afterwards. But here the whole work is laid together briefly which was much more largely and particularly related in the Kings. His zeal carried him out to do this, not only in Judah and Jerusalem, but in the cities of Israel too, as far as he had any influence upon them.
