Following are a number of back-translations as well as a sample translation for translators of 2 Samuel 15:31:

• Kupsabiny: “When David was told that Ahithophel was at/on the side of Absalom, he prayed to God that, ‘My God, turn the words Ahithophel to misguide Absalom.’” (Source: Kupsabiny Back Translation)
• Newari: “David heard [lit.: was caused to hear] that Ahithophel was among the advisors with Absalom. Then thinking like this, David prayed, "O LORD, please grant that Ahithophel’s advice will be made useless."” (Source: Newari Back Translation)
• Hiligaynon: “Now there was-someone who told David that Ahitofel is one of those who goes-along with Absalom. So David prayed, ‘LORD, make the advice of Ahitofel into nothing.’” (Source: Hiligaynon Back Translation)
• English: “Someone told David that Ahithophel had joined with those who were rebelling against David. So David prayed, ‘Yahweh, cause whatever Ahithophel suggests to Absalom that he should do to be considered to be foolish!’” (Source: Translation for Translators)
