Divrey Hayamim Bais 28:5 Meaning and Commentary

2 Chronicles 28:5

Wherefore the Lord his God delivered him into the hand of the
king of Syria
Whose name was Rezin, ( 2 Kings 16:5 ) , though that is an after expedition to this, which is there related. The Lord is called the God of Ahaz, because he was so of right; he had dominion over him, and ought to have been worshipped by him; and, besides, he was so by virtue of the national covenant between God and the people Ahaz was king of; and moreover, Ahaz professed he was his God, though in an hypocritical manner, and he forsook the true worship of him:

and they smote him, and carried away a great multitude of them
captives, and brought them to Damascus;
whereas in a later expedition, related in ( 2 Kings 16:5 ) , they did not succeed:

and he was also delivered into the hand of the king of Israel;
whose name was Pekah:

who smote him with a great slaughter;
as is next related.

3 Moreover he burned ketoret in the Gey Ben Hinnom, and burned his banim in the eish, after the to’avot of the Goyim whom Hashem had driven out before the Bnei Yisroel.

4 He also sacrificed and burned ketoret on the high places, and on the hilltops, and under every green tree.

5 Therefore Hashem Elohav delivered him into the yad Melech Aram; and they defeated him, and carried off a great multitude of prisoners, and brought them to Damascus. And he was also delivered into the yad Melech Yisroel, who inflicted on him makkah gedolah.

6 For Pekach ben Remalyahu slaughtered in Yehudah 120 elef in yom echad, which were all valiant men; because they had forsaken Hashem Elohei Avotam.

7 And Zichri, a gibbor of Ephrayim, slaughtered Ma’aseiyahu ben HaMelech, and Azrikam the Nagid HaBais, and Elkanah Mishneh HaMelech.
