16:10-16 God's altar had hitherto been kept in its place, and in use; but Ahaz put another in the room of it. The natural regard of the mind of man to some sort of religion, is not easily extinguished; but except it be regulated by the word, and by the Spirit of God, it produces absurd superstitions, or detestable idolatries. Or, at best, it quiets the sinner's conscience with unmeaning ceremonies. Infidels have often been remarkable for believing ridiculous falsehoods.
10-16. 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 (2Ki 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 (Ex 25:40; 26:30; 27:1; 1Ch 28:19). Urijah was one of the witnesses taken by Isaiah to bear his prediction against Syria and Israel (Isa 8:2).
