Albert Barnes Commentary Deuteronomy 2:8

"So we passed by from our brethren the children of Esau, that dwell in Seir, from the way of the Arabah from Elath and from Ezion-geber. And we turned and passed by the way of the wilderness of Moab." — Deuteronomy 2:8 (ASV)

Elath (Akaba) is at the northern extremity of the eastern arm of the Red Sea, and gives to that arm the name of the Elanitic Gulf. The name means “trees;” and is still justified by the grove of palm-trees at Akaba.
