Judges 2:12

And they forsook the Lord God of their fathers
The covenant God of their fathers, Abraham, Isaac, and Jacob, and of their more immediate ancestors; his worship they forsook, neglected his tabernacle, and the service of it:

which brought them out of the land of Egypt;
out of wretched misery and bondage there, with an high hand, and outstretched arm; and led them through the wilderness, and provided for them there, and brought them into the land of Canaan, a land flowing with milk and honey; but all these mercies were forgotten by them:

and followed other gods, of the gods of the people that [were] round
about them:
the gods of the Canaanites and Phoenicians, of the Egyptians, and of the Moabites, Amorites, and Edomites, that were round about them, on the borders of them; instead of one God they worshipped many, even all in or about the land of Canaan; so much given were they to idolatry:

and bowed themselves unto them;
giving them all religious worship and honour they were capable of:

and provoked the Lord to anger;
nothing is more provoking to him than idolatry; he being a jealous God, and will not bear any rival in worship, nor his glory to be given to another, to a strange god.
