2 Kings 16:8 - Joseph Benson’s Commentary on the Old and New Testaments

And Ahaz took the silver, &c. The treasures of the house of the Lord, and of the king's house, had been sent some years before by Jehoash to the king of Syria, 2 Kings 12:18. It seems, however, they had been well replenished again by the piety of his successors, Amaziah, Azariah, and especially Jotham. But what authority had Ahaz to dispose thus of the public money, and exhaust the treasures of both church and state, to gratify his new patron and guardian? We can only answer, that it is common for those, who have brought themselves into straits by one sin, to endeavour to extricate themselves by another. And those that have alienated themselves from God, will make no difficulty in alienating from him any other of his rights. In this instance, the sin itself was its own punishment; for, though the king of Assyria hearkened unto Ahaz, and, for his own ends, made a descent on Damascus, and took it, thereby giving a powerful diversion to the king of Syria, and obliging him to forego his design against Jerusalem; yet Ahaz made but an ill bargain, seeing he not only robbed the temple, and expended his own treasures, but enslaved both himself and his people to the king of Assyria.
