Jeremias 9:14 Meaning and Commentary

Jeremiah 9:14

But have walked after the imagination of their own heart
What their own hearts devised, chose, and were best pleased with; (See Gill on Jeremiah 7:24), and after Baalim;
the idols of the Gentiles; these they served and worshipped, and not the true God: which their fathers taught them;
which was so far from excusing them, that it was an aggravation of their sin, that they had continued in their wicked ways and idolatrous practices, from age to age, from one generation to another. This then was the cause of their calamity and destruction; they had forsaken the law of the Lord, and had broken that; they had chose their own ways, and had been guilty of idolatrous practices time out of mind; wherefore the Lord had shown much longsuffering and patience with them, and would now no longer forbear he was just and righteous in his doings.

Jeremias 9:14 In-Context

12 Who is the wise man, that he may understand this? and he that has the word of the mouth of the Lord to him, let him tell you wherefore the land has been destroyed, has been ravaged by fire like a desert, so that no one passes through it.
13 And the Lord said to me, Because they have forsaken my law, which I set before them, and have not hearkened to my voice;
14 but went after the lusts of their evil heart, and after the idols which their fathers taught them :
15 therefore thus saith the Lord God of Israel, Behold, I will feed them with trouble and will cause them to drink water of gall:
16 and I will scatter them among the nations, to them whom neither they nor their fathers knew; and I will send a sword upon them, until I have consumed them with it.
