וַיַּ֥ךְ דָּוִ֛יד אֶת־הֲדַדְעֶ֥זֶר מֶֽלֶךְ־צוֹבָ֖ה חֲמָ֑תָה בְּלֶכְתּ֕וֹ לְהַצִּ֥יב יָד֖וֹ בִּֽנְהַר־פְּרָֽת׃
瑣巴王哈大底謝去要在幼發拉底河確立他的勢力，大衛在哈馬擊敗了他。
Pirkei DeRabbi Eliezer
When David reigned, he wished to come into the land of Edom, but he was unable on account of the power of the covenant of Jacob's oath until he had broken that pillar. Concerning this, Solomon said: "And break in pieces their pillars" (Ex. 23:24). Afterwards he conquered the land of Edom, as it is said, "David smote also Hadadezer the son of Rehob, king of Zobah, as he went to recover his dominion at the river" (2 Sam. 8:3).
