A well in the Negev. Seven ewe lambs set apart. In Targum Pseudo-Jonathan on Genesis 21:32, the Aramaic preserves the ancient name of the place — Beira de-Sheva, the Well of the Seven Lambs — and the covenant struck there between Abraham and Abimelech.
The Targum of Pseudo-Jonathan renders the king's general as Phikol, chief of the host, and notes that both men return to the arʿa di-Phelishtaei, the land of the Philistines. The exchange has been formal: lambs given, oath sworn, borders acknowledged.
The older midrash reads the seven lambs as both a witness and a warning. Seven witnesses stand between two nations, and any breach of the oath will be remembered by them. The name of the place — Beersheba — becomes a living monument to the agreement.
The Maggidim took this verse as a quiet theology of peacemaking. Abraham is a covenant-maker long before Sinai. He does not conquer the Philistines. He treats with them. The takeaway: the righteous person plants wells and swears oaths, rather than building walls and raising armies. Seven lambs can hold a border longer than an army.
