Commentary for II Samuel 8:14

וַיָּ֨שֶׂם בֶּאֱד֜וֹם נְצִבִ֗ים בְּכָל־אֱדוֹם֙ שָׂ֣ם נְצִבִ֔ים וַיְהִ֥י כָל־אֱד֖וֹם עֲבָדִ֣ים לְדָוִ֑ד וַיּ֤וֹשַׁע יְהוָה֙ אֶת־דָּוִ֔ד בְּכֹ֖ל אֲשֶׁ֥ר הָלָֽךְ׃

And he put garrisons in Edom; throughout all Edom put he garrisons, and all the Edomites became servants to David. And the LORD gave victory to David whithersoever he went.
