Judges 6:3

Amalec was formerly widely dispersed through Arabia. Some dwelt to the south of the promised land, Exodus xvii., Numbers xiii. 3., 1 Kings xv. 6., and xxxi. 1. But these inhabited the eastern countries, concerning whom Balaam spoke, Numbers xxiv. 20. The Amalecites were scattered from Hevila upon the Euphrates, as far as the Red Sea and Sur, which is near Egypt, 1 Kings xv. 7., and xxvii. 8. The other eastern nations denote those who inhabited the desert Arabia, the Moabites, Ammonites, Idumeans, Cedarenians, &c., Isaias xi. 14., Jeremias xlix. 28., and Ezechiel viii. 7.
