Deuteronomy 23:5

because they met you not with bread and water in the way when you came from Mizraim, but hired against you Bileam bar Beor from Petho Chelmaya, which is built in the land of Aram upon the Phrat, to curse you;

BECAUSE THEY MET YOU NOT WITH BREAD AND WITH WATER. We find it stated [in Moses’ message to Sihon], Thou shalt sell me food for money, that I may eat; and give me water for money, that I may drink etc. as the children of Esau that dwell in Seir, and the Moabites that dwell in Ar did unto me. [This clearly states that the Moabites did not deprive them of bread and water, and in the verse before us it is mentioned that the Moabites did not meet them with bread and water!] Now, many scholars say that the Moabites did not meet them with bread and water, but that the Israelites bought it from them. But this is baseless, for it is adequate for a camp that they be sold [food] when they want to buy. Moreover, Israel came not within the border of Moab, and the Moabites brought them forth bread and water for money, and Scripture tells that the Moabites acted as did the children of Esau — why, then, were the Moabites forever banned [from the congregation of Israel] on account of this [for not having met them with bread and water], and of the Edomites it declared that we are not to abhor them? And Rabbi Abraham ibn Ezra stated that “the expression as the children of Esau … and the Moabites did unto me refers to the verse, Let me pass through thy land; I will go along by the highway,, Verse 27. but neither [the Edomites nor the Moabites] sold them bread and water. For the Israelites passed through Mount Seir [in Edom] and Ar [in Moab]; it was only to pass through his city where he dwelled that the king of Edom did not permit them — this being the sense of the expression, Thou shalt not pass ‘through me’ [but he did allow them entry through other parts of Edom].” This interpretation [of Ibn Ezra] is also baseless, for the Israelites said to the king of Edom, “Let me pass through thy land,”, Verse 17. The language there is: Let us pass, I pray thee, through thy land. and Edom refused to give Israel passage through his border., Verse 21. Thus they did not enter the border of Edom at all! And so it is written, And they journeyed from Mount Hor by the way to the Red Sea, to compass the land of Edom, 21:4. because they had to retreat by way of the Red Sea from Mount Hor which is on the border of the land of Edom, but they did not come into the land of Edom itself at all. Jephthah said it clearly: But when they came up from Egypt, and Israel walked through the wilderness unto the Red Sea, and …
