Chronicles I 5:25 Meaning and Commentary

1 Chronicles 5:25

And they transgressed against the God their fathers
Against his law, will, word, and ordinances, not only the half tribe of Manasseh, hut the Reubenites and Gadites also:

and went a whoring after the gods of the people of the land, whom God
destroyed before them;
that is, committed idolatry, which is spiritual fornication or whoredom; worshipped the idols either of the Amorites, who were destroyed by the Lord to make way for their first settlement; or of the Ishmaelites, whom they conquered, and whose land they dwelt in to the captivity.
