The treaty is signed in the morning. The Targum Pseudo-Jonathan adds a detail the Hebrew only whispers. "He broke off from the bridle of his ass, and gave one part to them for a testimony. And Izhak prayed for them, and they were enlarged" (Genesis 26:31).
Two elements stand out. First, the bridle. Second, the prayer.
A strip of leather as witness
In the ancient world, covenants often required a physical token — a stone, a pile of rocks, a divided animal. Here, Isaac snaps a strip from his ass's bridle and hands it to Abimelech. It is a small, practical thing. But the Targum treats it as formally significant: gave one part to them for a testimony. The leather is now a legal witness. The oath is bound in an object both parties carry.
The Torah often uses humble objects to seal eternity. A rainbow. A pillar. A strip of bridle. Pseudo-Jonathan honors the pattern.
And Isaac prayed for them
This is the line that the Targum adds without apology. Isaac prayed for them, and they were enlarged. Abimelech and his men, who had expelled Isaac from Gerar, now leave with the patriarch's prayer on their backs. The Aramaic suggests something like made prosperous or expanded — their households grew, their fortunes widened.
The rabbis taught that one who prays for another is answered first. But the Targum shows Isaac praying for his former adversaries and leaving them blessed. This is what tzedakah looks like on a covenant scale.
The takeaway: the Jewish ideal of peacemaking is not silence. It is blessing your enemies after they sign the paper.
