We acknowledge, O LORD, our wickedness, and the iniquity of our fathers: for we have sinned against you.
Read Chapter 14
He is saying, We and our ancestors have also neglected the precepts of God by the same insanity. The measure of our ancestors, therefore, is filled up in us, in such a way that whatever was coming due to them would be added to our measure. This is why it was said, concerning Judah: “May the Lord remember his fathers and may the sin of his mother not be forgotten! May they always be opposed to the Lord, and may their memory be eradicated from the earth!” - "Six Books on Jeremiah 3.39.1"
