In the words: if thou return, lies the reproach that in his complaint, in which his indignation had hurried him on to doubt God's faithfulness, Jeremiah had sinned and must repent. אשׁיבך is by many commentators taken adverbially and joined with the following words: then will I again cause thee to stand before me. But this adverbial use has been proved only for the Kal of שׁוּב, not for the Hiphil, which must here be taken by itself: then will I bring thee again, sc. into proper relations with me - namely, to stand before me, i.e., to be my servant. עמד , of the standing of the servant before his lord, to receive his commands, and so also of prophets, cf. 1 Kings 17:1; 1 Kings 18:15; 2 Kings 3:14, etc. In the words: if thou make to go forth, i.e., separate the precious from the vile, we have the figure of metal-refining, in course of which the pure metal is by fusion parted from the earthy and other ingredients mixed with it. The meaning of the figure is, however, variously understood. Some think here, unfittingly, of good and bad men; so Chald. and Rashi: if thou cause the good to come forth of the bad, turn the good into bad; or, if out of the evil mass thou cause to come forth at least a few as good, i.e., if thou convert them (Chr. B. Mich., Ros., etc.). For we cannot here have to do with the issue of his labours, as Graf well remarks, since this did not lie in his own power. Just as little is the case one of contrast between God's word and man's word, the view adopted by Ven., Eichh., Dahl., Hitz., Ew. The idea that Jeremiah presented man's word for God's word, or God's word mixed with spurious, human additions, is utterly foreign to the context; nay, rather it was just because he declared only what God imposed on him that he was so hard bested. Further, that idea is wholly inconsistent with the nature of true prophecy. Maurer has hit upon the truth: si quae pretiosa in te sunt, admixtis liberaveris sordibus, si virtutes quas habes maculis liberaveris impatientiae et iracundiae; with whom Graf agrees. כּפי (with the so-called כ verit.), as my mouth shalt thou be, i.e., as the instrument by which I speak, cf. Exodus 4:16. Then shall his labours be crowned with success. They (the adversaries) will turn themselves to thee, in the manner shown in Jeremiah 15:11, but thou shalt not turn thyself to them, i.e., not yield to their wishes or permit thyself to be moved by them from the right way. Jeremiah 15:20. After this reprimand, the Lord renews to him the promise of His most active support, such as He had promised him at his call, Jeremiah 1:18.; "to save thee" being amplified in Jeremiah 15:21.
