Numbers 20:21 Thus Edom refused to allow Israel to pass through his territory; so Israel turned away from him.
Deuteronomy 2:28,2928'You will sell me food for money so that I may eat, and give me water for money so that I may drink, only let me pass through on foot, 29just as the sons of Esau who live in Seir and the Moabites who live in Ar did for me, until I cross over the Jordan into the land which the LORD our God is giving to us.'
Hi bro,Numbers 21:4 And they journeyed from mount Hor by the way of the Red sea, to [u]compass[/u] [go round] the land of Edom: and the soul of the people was much discouraged because of the way.I think you're misunderstanding what actually happened. Esau had been given Mount Seir for a possession by God, and the children of Israel did not pass through, but around it. If you read the account being given by Moses at the beginning of Deu 2, you'll find God was instigating a change in Israel's relationship with the neighbours he mentions, beginning on that very day.25 This day will I begin to put the dread of thee and the fear of thee upon the nations [that are] under the whole heaven, who shall hear report of thee, and shall tremble, and be in anguish because of thee. 26 And I sent messengers out of the wilderness of Kedemoth unto Sihon king of Heshbon with words of peace, saying, 27 Let me pass through thy land: I will go along by the high way, I will neither turn unto the right hand nor to the left. 28 Thou shalt sell me meat for money, that I may eat; and give me water for money, that I may drink: only I will pass through on my feet; 29 (As the children of Esau which dwell in Seir, and the Moabites which dwell in Ar, did unto me;) until I shall pass over Jordan into the land which the LORD our God giveth us. 30 But Sihon king of Heshbon would not let us pass by him: for the LORD thy God hardened his spirit, and made his heart obstinate, that he might deliver him into thy hand, as [appeareth] this day. I think if you check the rest of the Old Testament for references to Esau, Edom and Seir, you'll pick up more of God's attitudes towards these cousins of Israel, whose forefather had so easily given up his birthright and blessing.
28 Thou shalt sell me meat for money, that I may eat; and give me water for money, that I may drink: only I will pass through on my feet; 29 (As the children of Esau which dwell in Seir, and the Moabites which dwell in Ar, did unto me;) until I shall pass over Jordan into the land which the LORD our God giveth us.
