Jeremiah 15:19-21

19Therefore, this is what the Lord says: If you return, I will take you back; you will stand in my presence. And if you speak noble words, rather than worthless ones, you will be my spokesman. It is they who must return to you; you must not return to them.

20Then I will make you a fortified wall of bronze to this people. They will fight against you but will not overcome you, for I am with you to save you and rescue you. This is the Lord’s declaration.

21I will rescue you from the power of evil people and redeem you from the grasp of the ruthless.
