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.
