Jeremiah 15:19-21

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. “I will save you from the hands of the wicked and deliver you from the grasp of the cruel.”
