I will go and return to my place, until they acknowledge their offense, And seek my face. In their affliction they will seek me earnestly."
"I will return ... till ..." The dual use of the term "till" in the Bible should be carefully observed.  It is used in two senses: (1) to indicate duration without regard to any sense of termination, as when Jacob said, "Thy servants have been keepers of cattle till this day," meaning not at all that the Jews were that day going out of the cattle business; and (2) in the sense of duration with an implied termination of it, as when Matthew wrote concerning Joseph and Mary that, "He knew her not till she brought forth a son, and called his name Jesus"  (Matthew 1:25).  The passage before us, like the one in  Romans 11:25, is enigmatical, in the sense that men cannot tell which usage of the word "till" appears in either passage.
