Jeremiah 15:18-20

Why is my pain unending and my wound grievous and incurable? You are to me like a deceptive brook, like a spring that fails. Therefore 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. I will make you a wall to this people, a fortified wall of bronze; they will fight against you but will not overcome you, for I am with you to rescue and save you,” declares the LORD.
