Jeremiah 15:18-19

18Why is my pain unending and my wound grievous and incurable? You are to me like a deceptive brook, like a spring that fails.

19Therefore this is what the LORD says: “If you repent, I will restore you that you may serve me; if you utter worthy, not worthless, words, you will be my spokesman. Let this people turn to you, but you must not turn to them.
