4 because they have forsaken me, and have estranged this place [from me], and have burned incense in it unto other gods, whom neither they nor their fathers have known, nor the kings of Judah; and have filled this place with the blood of innocents;

Matthew Henry's Commentary on Jeremiah 19:4

Commentary on Jeremiah 19:1-9

(Read Jeremiah 19:1-9)
