2 Kings 16:13

The king started using the new altar by making traditional offerings on it (see Leviticus 1–3; Numbers 15:1–10; 28:9–15, 24, 31; 2 Kings 6:8–23; 7:11–20). Unfortunately, these offerings on a non-religious altar by a leader lacking spiritual integrity made a mockery of their true spiritual significance.

And king Ahaz went to Damascus to meet Tiglath-pileser--This was a visit of respect, and perhaps of gratitude. During his stay in that heathen city, Ahaz saw an altar with which he was greatly captivated. Forthwith a sketch of it was transmitted to Jerusalem, with orders to Urijah the priest to get one constructed according to the Damascus model, and let this new altar supersede the old one in the temple. Urijah, with culpable complaisance, acted according to his instructions (Kg2 16:16). The sin in this affair consisted in meddling with, and improving according to human taste and fancy, the altars of the temple, the patterns of which had been furnished by divine authority (Exo 25:40; Exo 26:30; Exo 27:1; Ch1 28:19). Urijah was one of the witnesses taken by Isaiah to bear his prediction against Syria and Israel (Isa 8:2).

Though Ahaz had himself sacrificed in high places, on hills, and under every green tree (Kg2 16:4), yet God's altar had hitherto continued in its place and in use, and the king's burnt-offering and his meat-offering (Kg2 16:15) had been offered upon it by the priests that attended it; but here we have it taken away by wicked Ahaz, and another altar, an idolatrous one, put in the room of it - a bolder stroke than the worst of the kings had yet given to religion. We have here,
I. The model of this new altar, taken from one at Damascus, by the king himself, Kg2 16:10. The king of Assyria having taken Damascus, thither Ahaz went, to congratulate him on his success, to return him thanks for the kindness he had done him by this expedition, and, as his servant and son, to receive his commands. Had he been faithful to his God, he would not have needed to crouch thus meanly to a foreign power. At Damascus, either while viewing the rarities of the place, or rather while joining with them in their devotions (for, when he was there, he thought it no harm to do as they did), he saw an altar that pleased his fancy extremely, not such a plain old-fashioned one as that which he had been trained up in attendance upon at Jerusalem, but curiously carved, it is likely, and adorned with image-work; there were many pretty things about it which he thought significant, surprising, very charming, and calculated to excite his devotion. Solomon had but a dull fancy, he thought, compared with the ingenious artist that made this altar. Nothing will serve him but he must have an altar just like this: a pattern of it must be taken immediately; he cannot stay till he returns himself, but sends it before him in all haste, with orders to Urijah the priest to get one made exactly according to this model and have it ready against he came home. The pattern God showed to Moses in the mount or to David by the Spirit was not comparable to this pattern sent from Damascus. The hearts of idolaters walked after their eyes, which are therefore said to go a whoring after their idols; but the true worshippers worship the true God by faith.
II. The making of it by Urijah the priests, Kg2 16:11. This Urijah, it is likely, was the chief priest who at this time presided in the temple-service. To him Ahaz sent an intimation of his mind (for we read not of any express orders he gave him), to get an altar made by this pattern. And, without any dispute or objection, he put it in hand immediately, being perhaps as fond of it as the king was, at least being very willing to humour the king and desirous to curry favour with him. Perhaps he might have this excuse for gratifying the king herein, that, by this means, he might keep him to the temple at Jerusalem and prevent his totally deserting it for the high places and the groves. "Let us oblige him in this," thinks Urijah, "and then he will bring all his sacrifices to us; for by this craft we get our living." But, whatever pretence he had, it was a most base wicked thing for him that was a priest, a chief priest, to make this altar, in compliance with an idolatrous prince, for hereby, 1. He prostituted his authority and profaned the crown of his priesthood, making himself a servant to the lusts of men. There is not a greater disgrace to the ministry than obsequiousness to such wicked commands as this was. 2. He betrayed his trust. As priest, he was bound to maintain and defend God's institutions, and to oppose and witness against all innovations; and, for him to assist and serve the king in setting up an altar to confront the altar which by divine appointment he was consecrated to minister at, was such a piece of treachery and perfidiousness as may justly render him infamous to all posterity. Had he only connived at the doing of it, - had he been frightened into it by menaces, - had he endeavoured to dissuade the king from it, or but delayed the doing of it till he came home, that he might first talk with him about it, - it would not have been so bad; but so willingly to walk after his commandment, as if he were glad of the opportunity to oblige him, was such an affront to the God he served as was utterly inexcusable.
III. The dedicating of it. Urijah, perceiving that the king's heart was much upon it, took care to have it ready against he came down, and set it near the brazen altar, but somewhat lower and further from the door of the temple. The king was exceedingly pleased with it, approached it with all possible veneration, and offered thereon his burnt-offering, etc., Kg2 16:12, Kg2 16:13. His sacrifices were not offered to the God of Israel, but to the gods of Damascus (as we find Ch2 28:23), and, when he borrowed the Syrians' altar, no marvel that he borrowed their gods. Naaman, the Syrian, embraced the God of Israel when he got earth from the land of Israel to make an altar of.
IV. The removal of God's altar, to make room for it. Urijah was so modest that he put this altar at the lower end of the court, and left God's altar in its place, between this and the house of the Lord, Kg2 16:14. But that would not satisfy Ahaz; he removed God's altar to an obscure corner in the north side of the court, and put his own before the sanctuary, in the place of it. He thinks his new altar is much more stately, and much more sightly, and disgraces that; and therefore "let that be laid aside as a vessel in which there is no pleasure." His superstitious invention, at first, jostled with God's sacred institution, but at length jostled it out. Note, Those will soon come to make nothing of God that will not be content to make him their all. Ahaz durst not (perhaps for fear of the people) quite demolish the brazen altar and knock it to pieces; but, while he ordered all the sacrifices to be offered upon this new altar (Kg2 16:15), The brazen altar (says he) shall be for me to enquire by. Having thrust it out from the use for which it was instituted, which was to sanctify the gifts offered upon it, he pretends to advance it above its institution, which it is common for superstitious people to do. The altar was never designed for an oracle, yet Ahaz will have it for that use. The Romish church seemingly magnifies Christ's sacraments, yet wretchedly corrupts them. But some give another sense of Ahaz's purpose: "As for the brazen altar, I will consider what to do with it, and give order about it." The Jews say that, afterwards, of the brass of it he made that famous dial which was called the dial of Ahaz, Kg2 20:11. The base compliance of the poor-spirited priest with the presumptuous usurpations of an ill-spirited king is again taken notice of (Kg2 16:16): Urijah the priest did according to all that king Ahaz commanded. Miserable is the case of great men when those that should reprove them for their sins strengthen and serve them in their sins.

Ahaz went to Damascus - He had received so much help on the defeat of Rezin, that he went to Damascus to meet the king of Assyria, and render him thanks.
Ahaz sent to Urijah the priest the fashion of the altar - This was some idolatrous altar, the shape and workmanship of which pleased Ahaz so well that he determined to have one like it at Jerusalem. For this he had no Divine authority, and the compliance of Urijah was both mean and sinful. That Ahaz did this for an idolatrous purpose, is evident from Ch2 28:21-25 : "For he sacrificed to the gods of Damascus; - and he said, Because the gods of the kings of Syria help them, I will sacrifice to them, that they may help me. And he made high places to burn incense to other gods in every city of Judah."

And he burnt his burnt offering, and his meat offering,.... Which went together according to the law of God, and was imitated by the Heathens:

and poured his drink offering; a libation of wine, as probably it was, like what they used according to the Levitical law:

and sprinkled the blood of his peace offerings upon the altar; as used according to the same law; for all sorts of sacrifices were offered by idolaters, as by the people of God, in imitation of them.

For the heathens, and Ahaz, in imitation of them, offered the same sorts of offerings to their false gods which the Israelites did to the true, the devil being noted to be God’ s ape in his worship.

Ahaz paid Tiglath-pileser a visit in Damascus, "to present to him his thanks and congratulations, and possibly also to prevent a visit from Tiglath-pileser to himself, which would not have been very welcome" (Thenius). The form דּוּמשׂק is neither to be altered into דּמּשׂק nor regarded as a copyist's error for דּרמשׂק, as we have several words in this chapter that are formed with dull Syriac u-sound. The visit of Ahaz to Damascus is simply mentioned on account of what follows, namely, that Ahaz saw an altar there, which pleased him so much that he sent a picture and model of it "according to all the workmanship thereof," i.e., its style of architecture, to Urijah the priest (see Isa 8:2), and had an altar made like it for the temple, upon which, on his return to Jerusalem, he ordered all the burnt-offerings, meat-offerings, and drink-offerings to be presented. The allusion here is to the offerings which he commanded to be presented for his prosperous return to Jerusalem.
