Ellicott's Commentary On The Whole Bible
1 Chronicles 18:11
He brought. — Samuel, “dedicated.” Chronicles avoids the tautology.
These nations. — The nations — scil., “whom he had reduced” (Samuel).
From Edom. — Samuel, “from Aram,” but LXX., Syriac, and Arabic, “Edom;” (Targum and Vulg., “Aram”). All the versions read “Edom” here, which appears correct. Edom and Moab were conterminous, and the reference includes all the nations whom David conquered and despoiled.
And from Amalek may refer to 1 Samuel 30:16, seq., but more probably to an unrecorded campaign. Samuel adds, “and from the spoil of Hadadezer son of Rehob, king of Zobah,” which Chronicles omits, as implied already in 1 Chronicles 18:7.
