Charles Ellicott Commentary Jeremiah 19:5

"and have built the high places of Baal, to burn their sons in the fire for burnt-offerings unto Baal; which I commanded not, nor spake it, neither came it into my mind:" — Jeremiah 19:5 (ASV)

The high places of Baal. —Baal, as in Jeremiah 2:23, is identified with Molech, and the terms in which the guilt of the people and its punishment are described are all but identical with those of Jeremiah 7:31-32. The fact that such sacrifices were offered is indicated in Psalm 106:37-38.
