וַיַּ֥ךְ דָּוִ֛יד אֶת־הֲדַדְעֶ֥זֶר מֶֽלֶךְ־צוֹבָ֖ה חֲמָ֑תָה בְּלֶכְתּ֕וֹ לְהַצִּ֥יב יָד֖וֹ בִּֽנְהַר־פְּרָֽת׃
און דוד האָט געשלאָגן הַדַדעֶזֶר דעם מלך פֿון צוֹבֿה אין חַמָת, בעת ער איז געגאַנגען אױפֿשטעלן זײַן אױבערהאַנט בײַם טײַך פּרָת.
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).
