Jeremiah
Jeremiah 19:4ESV·traditional attribution

Because the people have forsaken me and have profaned this place by making offerings in it to other gods whom neither they nor their fathers nor the kings of Judah have known; and because they have filled this place with the blood of innocents,

John Calvin Reformed @genevareformer

The reason is given why God would so severely deal with that place. We indeed know that hypocrites are ever ready with their answer; as soon as God threatens them, they bark and bring forward their evasions. The Prophet then shews that the judgment announced would be just, lest the Jews should pretend that it was extreme.

Matthew Henry Presbyterian @wholebiblehenry

The corruption of man having made it necessary that precept should be upon precept, and line upon line (so unapt are we to receive, and so very apt to let slip, the things of God), the grace of God has provided that there shall be, accordingly, precept upon precept, and line upon line, that those who are irreclaimable may be inexcusable.

John Gill Reformed Baptist @doctorgill

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.
