Following are a number of back-translations as well as a sample translation for translators of Jeremiah 3:20:

• Kupsabiny: “But you fled from me,
  like a woman who has refused her husband and flees from (him).
  I God have spoken!” (Source: Kupsabiny Back Translation)
• Hiligaynon: “But, like a wife who is deceitful to her husband, you (plur.) are the same to me, people of Israel. I, the LORD, (am) the-(one) saying this.’” (Source: Hiligaynon Back Translation)
• English: “But you have abandoned me like wives who have abandoned their husbands.’ ’
  That is what Yahweh said, and I told it to the people of Israel.” (Source: Translation for Translators)
