Hastings' Dictionary of the Bible (1898) & Schaff's Bible Dictionary
HOR-HAGID'GAD (mountain of the cleft), a camping-place of the Israelites in the desert, Num 33:32; apparently the same as Gudgodah, Deut 10:7, though Wilton regards the latter as a valley and the former as a mountain near it; Robinson notes on his map a Wady Ghudoghah west of the Arabah; possibly identical with this place.
Hitchcock's Bible Names (1869)
