Genesis 36:20-30

The Horites the aboriginal inhabitants of the country "the sons of Seir, the Horite," were possibly so called from the word ḥor, "a hole"; cf. 1 Samuel 13:6; 1 Samuel 14:11. This derivation has long been maintained, and is possibly correct, the Horites being regarded as troglodytes, or cave-dwellers. In Obadiah 1:3 Edom is apostrophized, "O thou that dwellest in the clefts of the rock." On the other hand another derivation has recently commended itself, Hor being identified with the Egyptian Haruwhich is found in Egyptian inscriptions for "Syria." But there is good support from the rocks of Petra and the excavations at Gezer for the "cave-dweller" explanation of the word.
