Jeremiah 19:4

4 because that they have forsaken Me, and make known this place, and make perfume in it to other gods, that they knew not, they and their fathers, and the kings of Judah, and they have filled this place [with] innocent blood,

Jeremiah 19:4 Meaning and Commentary

Jeremiah 19:4

Because they have forsaken me
My worship, as the Targum; they had apostatized from God, relinquished his service, neglected and despised his word and ordinances, and left the religion they had been brought up in, and was agreeable to the will of God. This, with what follows, contain reasons of the Lord's threatening them to bring evil upon them, as before: and have estranged this place;
or made a strange place of it, so that it could scarcely be known to be the same, nor would the Lord own it as his; meaning either the city of Jerusalem, to which the prophet was near, and could point to it; or the temple, which was in sight, and which they had strangely abused, by offering strange sacrifices to strange gods; or the valley of Hinnom, the spot he was upon, and which they had alienated from its original use: and have burnt incense in it unto other gods;
to strange gods, the gods of the Gentiles; and this they did both in the city of Jerusalem and in the temple, and very probably in the valley of Hinnom, where they sacrificed their children: gods whom neither they nor their fathers have known, nor the kings of Judah;
of whose wisdom, power, and goodness, neither they nor their fathers before them, nor any of their kings, had had any instance; and whose help and assistance, in times of danger and difficulty, they had had no experience of; and, till now, neither they nor their ancestors had ever owned them, or acknowledged them; nor scarce had heard of their names; nor any of their pious kings, as David, Asa, Jehoshaphat, Hezekiah, and Josiah: and have filled this place with the blood of innocents;
young children that were sacrificed here to idols, as they were in the valley of Hinnom, which seems to be the place principally intended; so that they were not only guilty of idolatry, but of murder; and of the murder of innocent creatures, and even, of their own babes; which was shocking and unheard of cruelty!

Jeremiah 19:4 In-Context

2 and thou hast gone forth unto the valley of the son of Hinnom, that [is] at the opening of the gate of the pottery, and hast proclaimed there the words that I speak unto thee,
3 and hast said, Hear a word of Jehovah, ye kings of Judah, and inhabitants of Jerusalem, Thus said Jehovah of Hosts, God of Israel: `Lo, I am bringing in evil on this place, at which the ears of every one who is hearing it do tingle,
4 because that they have forsaken Me, and make known this place, and make perfume in it to other gods, that they knew not, they and their fathers, and the kings of Judah, and they have filled this place [with] innocent blood,
5 and have built the high places of Baal to burn their sons with fire, burnt-offerings to Baal, that I commanded not, nor spake of, nor did it come up on My heart.
6 `Therefore, lo, days are coming -- an affirmation of Jehovah -- and this place is not called any more, Tophet, and Valley of the son of Hinnom, but, Valley of slaughter.
