John Gill Commentary Jeremiah 44:5

"But they hearkened not, nor inclined their ear to turn from their wickedness, to burn no incense unto other gods." — Jeremiah 44:5 (ASV)

But they listened not, nor inclined their ear to the prophets sent to them; to God by the prophets; to the words of his mouth, particularly to the above pathetic expostulation with them; at least, if they heard the words said, they did not attend to them; they had not such an effect upon them, nor were they wrought upon by them.

To turn from their wickedness, to burn no incense to other gods; to turn from their sins in general, and from their idolatry in particular; one instance of which is given, and which is put for the whole of idolatrous worship.
