Judges 2:20

And the anger of the Lord was hot against Israel
As at first, so whenever they fell into idolatry; see ( Judges 2:14 ) ;

and he said, because this people have transgressed my covenant which I
commanded their fathers;
made at Sinai, in which they were enjoined to have no other gods before him:

and have not hearkened to my voice;
in his commands, and particularly what related to his worship and against idolatry.
