The passage you’re probably looking for is Jeremiah 31:37 , which says God would not reject Israel so long as the heavens and earth stand. It’s often paraphrased as God saying He would not “turn away” from Israel.

Closest matches

  • Jeremiah 31:37 : the strongest match for “I will turn my back on you” language about Israel.
  • Jeremiah 3:12 : God tells faithless Israel to return and says, “I will not be angry forever.”
  • Jeremiah 21:4 : this is about God turning back the weapons of war in Jerusalem, not the exact phrase you quoted.

Important note

Your wording sounds like a paraphrase rather than a direct quote. In most Bibles, the exact idea is expressed more like God not casting off Israel or not rejecting Israel forever.
