Chronicles II 28:6 Meaning and Commentary

2 Chronicles 28:6

For Pekah son of Remaliah
Who was at this time king of Israel:

slew in Judah an hundred and twenty thousand in one day,
which were all

valiant men;
a great slaughter to be made at one time, and of valiant men, but not so great as that in ( 2 Chronicles 13:17 ) ,

because they had forsaken the Lord God of their fathers;
this was not a reason with Pekah for slaying them, he himself being an idolater, but why the Lord suffered them to be slain by him.
