We may well imagine the bad posture of affairs in Jerusalem during Athaliah's six years' usurpation, and may wonder that God permitted it and his people bore it so long; but after such a dark and tedious night the returning day in this revolution was the brighter and the more welcome. The continuance of David's seed and throne was what God had sworn by his holiness (Psa 89:35), and an interruption was no defeasance; the stream of government here runs again in the right channel. The instrument and chief manager of the restoration is Jehoiada, who appears to have been, 1. A man of great prudence, who reserved the young prince for so many years till he was fit to appear in public, and till the nation had grown weary of the usurper, who prepared his work beforehand, and then effected it with admirable secresy and expedition. When God has work to do he will qualify and animate men for it. 2. A man of great interest. The captains joined with him, Ch2 23:1. The Levites and the chief of the fathers of Israel came at his call to Jerusalem (Ch2 23:2) and were there ready to receive his orders. See what a command wisdom and virtue will give men. The Levites and all Judah did as Jehoiada commanded (Ch2 23:8), and, which is strange, all that were entrusted with the secret kept their own counsel till it was executed. Thus the words of the wise are heard in quiet, Ecc 9:17. 3. A man of great faith. It was not only common equity (much less his wife's relation to the royal family) that put him upon this undertaking, but a regard to the word of God, and the divine entail of the crown (Ch2 23:3): The king's son shall reign, must reign, as the Lord hath said. His eye to the promise, and dependence upon that, added a great deal of glory to this undertaking. 4. A man of great religion. This matter was to be done in the temple, which might occasion some breach of rule, and the necessity of the case might be thought to excuse it; but he gave special order that none of the people should come into the house of the Lord, but the priests and Levites only, who were holy, upon pain of death, Ch2 23:6, Ch2 23:7. Never let sacred things be profaned, no, not for the support of civil rights. 5. A man of great resolution. When he had undertaken this business he went through with it, brought out the king, crowned him, and gave him the testimony, Ch2 23:11. He ventured his head, but it was in a good cause, and therefore he went on boldly. It is here said that his sons joined with him in anointing the young king. One of them, it is likely, was that Zechariah whom Joash afterwards put to death for reproving him (Ch2 24:20), which was so much the more ungrateful because he bore a willing part in anointing him.

God save the king - May the king live! See on Kg2 11:12 (note).

Then they brought out the king's son, and put upon him the crown, and gave him the testimony--Some think that the original word rendered "testimony," as its derivation warrants, may signify here the regalia, especially the bracelet (Sa2 1:10); and this view they support on the ground that "gave him" being supplemented, the text properly runs thus, "put upon him the crown and testimony." At the same time, it seems equally pertinent to take "the testimony" in the usual acceptation of that term; and, accordingly, many are of opinion that a roll containing a copy of the law (Deu 17:18) was placed in the king's hands, which he held as a scepter or truncheon. Others, referring to a custom of Oriental people, who when receiving a letter or document from a highly respected quarter, lift it up to their heads before opening it, consider that Joash, besides the crown, had the book of the law laid upon his head (see Job 31:35-36).

God save the king--literally, "Long live the king."
