Matthew Henry on 2 Chronicles 28:16–end
Here is, I. The great distress which the kingdom of Ahaz was reduced to for his sin. In general, 1. The Lord brought Judah low, Ch2 28:19. They had lately been very high in wealth and power; but God found means to bring them down, and make them as despicable as they had been formidable. Those that will not humble themselves under the word of God will justly be humbled by his judgments. Iniquity brings men low, Psa 106:43. 2. Ahaz made Judah naked.

Adam Clarke on 2 Chronicles 28:21
But he helped him not - He did him no ultimate service. See the note on Kg2 16:9.
After Kg2 16:15, the 23d, 24th, and 25th verses are introduced before the 16th, in the Syriac and Arabic, and the 22d verse is wholly wanting in both, though some of the expressions may be found in the twenty-first verse.
John Gill on 2 Chronicles 28:21
For Ahaz took away a portion out of the house of the Lord, and out of the house of the king, and of the princes,.... A part out of the treasures of the temple, and a part out of his own treasures, and another which he levied upon his nobles:
and gave it unto the king of Assyria; sent it to him as a present, to engage him on his side, and assist him against his enemies, 2 Kings 16:10.
but he helped him not; See Gill on 2 Chronicles 28:20.
