Indeed the army of the Arameans came with a small number of men; yet the Lord delivered a very great army into their hands, because they had forsaken the Lord, the God of their fathers. Thus they executed judgment on Joash.

For Pekah the son of Remaliah slew in Judah 120,000 in one day, all valiant men, because they had forsaken the Lord God of their fathers.
