Jeremiah 2:5

Thus saith the Lord, what iniquity have your fathers found in me,.... What injustice or injury has been done them? there is no unrighteousness in God, nor can any be done by him; or what unfaithfulness, or want of truth and integrity in performing promises, had they found in him? he never suffers his faithfulness to fail, or any of the good things he has promised. So the Targum,

"what falsehood have your fathers found in my word?''

none at all; God is a covenant keeping God:

that they are gone far from me; from my fear, as the Chaldee paraphrase; from the word and worship, and ways of God:

and have walked after vanity; after idols, the vanities of the Gentiles, Jeremiah 14:22:

and are become vain? in their imaginations and in their actions, in their knowledge and in their practice, worshipping idols, as well as guilty of many other sins.
