II Kings 12:1

(1-5). Reign of Joash. - Kg2 12:1 (1, 2). His age on ascending the throne, viz., seven years (cf. Kg2 11:4). - Commencement and length of his reign. His mother's name was Zibiah of Beersheba. Kg2 12:2 (3). Joash did that which was right in the eyes of the Lord וגו אשׁר כּל־ימין, "all his days that," etc., i.e., during the whole period of his life that Jehoiada instructed him (for אשׁר after substantives indicating time, place, and mode, see Ewald, 331, c., 3; and for the use of the suffix attached to the noun defined by וגו אשׁר, compare Kg2 13:14); not "all his life long, because Jehoiada had instructed him," although the Athnach under ימין favours this view. For Jehoiada had not instructed him before he began to reign, but he instructed him after he had been raised to the throne at the age of seven years, that is to say, so long as Jehoiada himself lived. The יהוידע כּל־ימי of the Chronicles is therefore a correct explanation. But after Jehoiada's death, Joash yielded to the petitions of the princes of Judah that he would assent to their worshipping idols, and at length went so far as to stone the son of his benefactor, the prophet Zechariah, on account of his candid reproof of this apostasy (Ch2 24:17-22). Kg2 12:3 (4). But the worship on the high places was not entirely suppressed, notwithstanding the fact that Jehoiada instructed him (on this standing formula see the Comm. on Kg1 15:14).

The general account here given of Joash is, 1. That he reigned forty years. As he began his reign when he was very young, he might, in the course of nature, have continued much longer, for he was cut off when he was but forty-seven years old, Kg2 12:1. 2. That he did that which was right as long as Jehoiada lived to instruct him, Kg2 12:2. Many young men have come too soon to an estate - have had wealth, and power, and liberty, before they knew how to use them - and it has been of bad consequence to them; but against this danger Joash was well guarded by having such a good director as Jehoiada was, so wise, and experienced, and faithful to him, and by having so much wisdom as to hearken to him and be directed by him, even when he was grown up. Note, It is a great mercy to young people, and especially to young princes, and all young men of consequence, to be under good direction, and to have those about them that will instruct them to do that which is right in the sight of the Lord; and they then do wisely and well for themselves when they are willing to be counselled and ruled by such. A child left to himself brings his mother to shame, but a child left to such a tuition may bring himself to honour and comfort. 3. That the high places were not taken away, Kg2 12:3. Up and down the country they had altars both for sacrifice and incense, to the honour of the God of Israel only, but in competition with, and at least in tacit contempt of, his altar at Jerusalem. These private altars, perhaps, had been more used in the late bad reigns than formerly, because it was not safe to go up to Jerusalem, nor was the temple-service performed as it should have been; and, it may be, Jehoiada connived at them, because some well-meaning people were glad of them when they could not have be…

12:1 Joash reigned from 835 to 796 BC.
