The tabernacles of Edom. Edom was always among the bitterest of Israel's enemies, and naturally took a part in almost every combination that was made against them. Though sometimes subjugated (2 Samuel 8:14; 1 Kings 11:15, 1 Kings 11:16), it continued hostile during the whole period of Israelite and Jewish history.
Hence the constant denunciations of the prophets (Isaiah 11:14; Jeremiah 27:3; Jeremiah 49:7-22; Ezekiel 25:12-14; Joel 3:19; Amos 9:12; Obadiah 1:6-18; Malachi 1:4). And the Ishmaelites. The Ishmaelites were the chief inhabitants of Northern Arabia (Genesis 25:13-18).
They do not often appear among Israel's enemies. Of Moab. Moab, on the contrary, is a persistent adversary (see Numbers 22:6; 3:12-30; 1 Samuel 14:47; 2 Samuel 8:2; 2 Kings 1:1; 2 Kings 3:4-27; 26:2; 2 Chronicles 20:1-10).
And the Hagarenes. The "Hagarenes," or "Hagarites," are only mentioned here and in 1 Chronicles 5:10, 1 Chronicles 5:19-22. They were probably a branch of the Ishmaelites, named after Hagar, Ishmael's mother (Genesis 25:12).
Their name occurs among those of Aramman tribes in the Assyrian inscriptions.
