Numbers 20:18

Verse 18. Edom, the people who dwelt near Mount Hor. Those of Seir, lying more to the west, ( D.) granted them leave to pass, and to buy food. Deuteronomy 2:28. 29. Grotius maintains, that the Hebrews might justly have forced a passage upon this refusal; as Saint Augustine (q. 44,) says, that they might lawfully have waged war upon the Amorrhites, on the like occasion; and the holy wars have been defended on the same plea, because the Saracens would not suffer the Christians to go in pilgrimage to the holy land. See Mare, lib. i. 1. But Selden (Mare. claus. 20) asserts, that princes have a right ot hinder others from passing through their territories; and Saint Augustine only excepts one case, when they are sure the strangers can or will do no harm. But how can they obtain this assurance? Calmet answers, the long continuance of the Hebrews near the confines of Seir, without offering any molestation, and their being conducted by so holy a general, might give the people of Hor sufficient security. But at any rate the Israelites could not wage war upon them for refusing a passage, since they were expressly forbidden by God: Stir not against them, (Deuteronomy 2:5,) the people of Seir, nor against any of the Idumeans, the children of Esau, who had taken possession of the country of Horrhites. Genesis 14:6. The Hebrews seem to have been convinced of this, otherwise they would not have feared their multitudes, nor taken such a circuitous road. The angel in the cloud directed them to proceed, without molesting their territory. They went, therefore, towards the south, round the land of the Idumeans, who dwelt near the Dead Sea. Bible.
