Jeremiah 7:5-8

5If you really change your ways and your actions and deal with each other justly, 6if you do not oppress the foreigner, the fatherless or the widow and do not shed innocent blood in this place, and if you do not follow other gods to your own harm, 7then I will let you live in this place, in the land I gave your ancestors for ever and ever.

8But look, you are trusting in deceptive words that are worthless.
