אִם־תָּשׁ֨וּב יִשְׂרָאֵ֧ל ׀ נְאֻם־יְהוָ֛ה אֵלַ֖י תָּשׁ֑וּב וְאִם־תָּסִ֧יר שִׁקּוּצֶ֛יךָ מִפָּנַ֖י וְלֹ֥א תָנֽוּד׃
If thou wilt return, O Israel, Saith the LORD, Yea, return unto Me; and if thou wilt put away thy detestable things out of My sight, and wilt not waver;
Rashi on Jeremiah
If you return, O Israel with this repentance, to Me, you will return to your original glory and greatness.
Rashi on Jeremiah
and if you remove your detestable things from My Presence Then you shall not wander to go out in exile.
