| Gill's Exposition of the Entire Bible In the seventeenth year of Pekah the son of Remaliah Ahaz the son of Jotham king of Judah began to reign. Jotham began to reign in the second of Pekah, and he reigned sixteen years, and therefore his last year would fall in the eighteenth of Pekah; but as his first year might be at the beginning of the second of Pekah, his last was towards the end of the seventeenth of Pekah's, as here; see 2 Kings 15:32.
Keil and Delitzsch Biblical Commentary on the Old TestamentOn the time mentioned, "in the seventeenth year of Pekah Ahaz became king" see at 2 Kings 15:32. The datum "twenty years old" is a striking one, even if we compare with it 2 Kings 18:2. As Ahaz reigned only sixteen years, and at his death his son Hezekiah became king at the age of twenty-five years (2 Kings 18:2), Ahaz must have begotten him in the eleventh year of his age. It is true that in southern lands this is neither impossible nor unknown, (Note: In the East they marry girls of nine or ten years of age to boys of twelve or thirteen (Volney, Reise, ii. p. 360). Among the Indians husbands of ten years of age and wives of eight are mentioned (Thevenot, Reisen, iii. pp. 100 and 165). In Abyssinia boys of twelve and even ten years old marry (Rppell, Abessynien, ii. p. 59). Among the Jews in Tiberias, mothers of eleven years of age and fathers of thirteen are not uncommon (Burckh. Syrien, p. 570); and Lynch saw a wife there, who to all appearance was a mere child about ten years of age, who had been married two years already. In the epist. ad N. Carbonelli, from Hieronymi epist. ad Vitalem, 132, and in an ancient glossa, Bochart has also cited examples of one boy of ten years and another of nine, qui nutricem suam gravidavit, together with several other cases of a similar kind from later writers. Cf. Bocharti Opp. i.((Geogr. sacr.) p. 920, ed. Lugd. 1692.) but in the case of the kings of Judah it would be without analogy. The reading found in the lxx, Syr., and Arab. at 2 Chronicles 28:1, and also in certain codd., viz., five and twenty instead of twenty, may therefore be a preferable one. According to this, Hezekiah, like Ahaz, was born in his father's sixteenth year.
Geneva Study BibleIn the seventeenth year of Pekah the son of Remaliah {a} Ahaz the son of Jotham king of Judah began to reign. (a) This was a wicked son of a godly father, as of him again came godly Hezekiah, and of him wicked Manasseh, save that God in the end showed him mercy. Thus we see how uncertain it is to depend on the dignity of our fathers.
Jamieson-Fausset-Brown Bible CommentaryCHAPTER 16 2Ki 16:1-16. Ahaz' Wicked Reign over Judah. 1-4. Ahaz . did not that which was right in the sight of the Lord-[See on [345]2Ch 28:1.] The character of this king's reign, the voluptuousness and religious degeneracy of all classes of the people, are graphically portrayed in the writings of Isaiah, who prophesied at that period. The great increase of worldly wealth and luxury in the reigns of Azariah and Jotham had introduced a host of corruptions, which, during his reign, and by the influence of Ahaz, bore fruit in the idolatrous practices of every kind which prevailed in all parts of the kingdom (see 2Ch 28:24).
Matthew Henry's Concise Commentary16:1-9 Few and evil were the days of Ahaz. Those whose hearts condemn them, will go any where in a day of distress, rather than to God. The sin was its own punishment. It is common for those who bring themselves into straits by one sin, to try to help themselves out by another.
Matthew Henry's Whole Bible CommentaryChapter 16 This chapter is wholly taken up with the reign of Ahaz; and we have quite enough of it, unless it were better. He had a good father, and a better son, and yet was himself one of the worst of the kings of Judah. I. He was a notorious idolater (v. 1-4). II. With the treasures of the temple, as well as his own, he hired the king of Assyria to invade Syria and Israel (v. 5-9). III. He took pattern from an idol's altar which he saw at Damascus for a new altar in God's temple (v. 10-16). IV. He abused and embezzled the furniture of the temple (v. 17, 18). And so his story ends (v. 19, 20). Verses 1-4 We have here a general character of the reign of Ahaz. Few and evil were his days-few, for he died at thirty-six-evil, for we are here told, 1. That he did not that which was right like David (v. 2), that is, he had none of that concern and affection for the instituted service and worship of God for which David was celebrated. He had no love for the temple, made no conscience of his duty to God, nor had any regard to his law. Herein he was unlike David; it was his honour that he was of the house and lineage of David, and it was owing to God's ancient covenant with David that he was now upon the throne, which aggravated his wickedness; for he was a reproach to that honourable name and family, which therefore was really a reproach to him (Degeneranti genus opprobrium-A good extraction is a disgrace to him who degenerates from it), and though he enjoyed the benefit of David's piety he did not tread in the steps of it. 2. That he walked in the way of the kings of Israel (v. 3), who all worshipped the calves. He was not joined in any affinity with them, as Jehoram and Ahaziah were with the house of Ahab, but, ex mero motu-without any instigation, walked in their way. The kings of Israel pleaded policy and reasons of state for their idolatry, but Ahaz had no such pretence: in him it was the most unreasonable impolitic thing that could be. They were his enemies, and had proved enemies to themselves too by their idolatry; yet he walked in their way. 3. That he made his sons to pass through the fire, to the honour of his dunghill-deities. He burnt them, so it is expressly said of him (2 Chr. 28:3), burnt some of them, and perhaps made others of them (Hezekiah himself not excepted, though afterwards he was never the worse for it) to pass between two fires, or to be drawn through a flame, in token of their dedication to the idol. 4. That he did according to the abominations of the heathen whom the Lord had cast out. it was an instance of his great folly that he would be guided in his religion by those whom he saw fallen into the ditch before his eyes, and follow them; and it was an instance of his great impiety that he would conform to those usages which God had declared to be abominable to him, and set himself to write after the copy of those whom God had cast out, thus walking directly contrary to God. 5. That he sacrificed in the high places, v. 4. If his father had but had zeal enough to take them away, the debauching of his sons might have been prevented; but those that connive at sin know not what dangerous snares they lay for those that come after them. He forsook God's house, was weary of that place where, in his father's time, he had often been detained before the Lord, and performed his devotions on high hills, where he had a better prospect, and under green trees, where he had a more pleasant shade. It was a religion little worth, which was guided by fancy, not by faith. |
