But have walked after the imagination of their own heart, and after Baalim, which their fathers taught them:
Walked after the imagination of their own heart - (Jeremiah 7:24).
Baalim - plural of Baal, to express his supposed manifold powers.
Which their fathers taught them - (Galatians 1:14, "I ... profited in the Jews' religion above many my equals in mine own nation, being more exceedingly zealous of the traditions of my fathers;" 1 Peter 1:18.) We are not to follow the errors of the fathers, but the authority of Scripture and of God (Jerome).
