Imagination, or stubbornness and obstinacy: see Jer_7:24.
Baalim: see Jer_2:23. The prophet doth not charge them with new crimes, but with their tenacious sticking to their idolatry.
Which their fathers taught them: see Jer_7:18. It seems they might partly thank their education for it, as well as their own natural perverseness: hence we should learn to follow God’s counsel in the Scriptures, and not blindly follow our fathers’ counsel, precepts, or examples, or our own will, which is the worst guide.
