Jeremiah 15:19

Therefore thus says the Lord [to Jeremiah]: If you return [and give up this mistaken tone of distrust and despair], then I will give you again a settled place of quiet and safety, and you will be My minister; and if you separate the precious from the vile [cleansing your own heart from unworthy and unwarranted suspicions concerning God''s faithfulness], you shall be My mouthpiece. [But do not yield to them.] Let them return to you--not you to [the people].
