If thou wilt return, O Israel, saith the LORD, return unto me: and if thou wilt put away thine abominations out of my sight, then shalt thou not remove.
If thou wilt return, O Israel, saith the Lord, return unto me - play on words. "If thou wouldest return to thy land, (thou must first) return thy (by conversion and repentance) to me."
Not remove - no longer be an unsettled wanderer in a strange land. So Cain (Genesis 4:12; Genesis 4:14).
