AND MOAB WAS SORE AFRAID OF THE PEOPLE. The meaning of this is [that Moab stood in great fear] because they [the Israelites] were many,1The Hebrew text reads: ki rav hu. This can be interpreted as “although they were many,” in which case the reference would be to the Moabites, [the word ki meaning “although”]. The meaning of the verse would thus be: “And Moab was sore afraid of the Israelites although they [the Moabites] were many, Ramban, wishing to exclude this interpretation, for the reason cited in the text, explains that the word ki here means “because”; hence the pronoun hu — “they” [they were many] refers to the Israelites. for Moab was small among the nations;2See Obadiah 1:2. and it was not an ancient people, like the Canaanites, the Amorites and other [nations of the] sons of Noah. Therefore they [the Moabites] were greatly afraid of the people who outnumbered them exceedingly, for they were fruitful, and increased abundantly, and waxed3Exodus 1:7. greater than the Moabites. And they were furthermore overcome with dread because of the children of Israel,4Verse 3 here. — Hence the double expression of the verse: And Moab was sore afraid … and Moab was overcome with dread. for they had heard of the great wonders that had happened to them and their fathers. Now Moab knew that Israel would not take their land from them, since they had sent to them [offering peace]5Judges 11:17: And in like manner he sent unto the king of Moab … just as they had sent to Sihon, [asking permission only to pass through their land], saying, until I shall pass over the Jordan into the Land which the Eternal our G-d giveth us.6Deuteronomy 2:29. Or it is also possible that they had heard of G-d’s prohibition, when He said to the Israelites, Be not at enmity with Moab.7Ibid., Verse 9. Therefore they said to the elders of Midian: “Even though the Israelites will not capture our land, they will lick up because of their great numbers all that is round about us, as the ox licketh up the grass of the field,8Verse 4 here. and they will capture all [the lands] that surround us, just as they did to the two Amorite kings, and they will make us servants to do taskwork.”9Joshua 16:10.
Or HaChaim
לא יבא עמוני ומואבי בקהל השם, "Neither an Ammonite nor a Moabite may become members of the Jewish people, etc." The reason which the Torah gives for denying the male members of these tribes the right to convert to Judaism, i.e. that they did not come forward with bread and water to assist the Israelites when the latter came out of Egypt is hard to understand. Does not the Torah itself testify in Deut. 2,29: "as did the members of the tribe of Esau and the Moabites?" The reference is to both of these nations having sold provisions to the Israelites at the time. Rashi explains the apparent contradiction as 1) the verse in 2,29 referring to the Israelites' offer to buy food in return for money (2,28). 2) What is written here refers to the fact that they hired Bileam to curse the Jewish people and to lead it into sin at the end of the 40 years trek through the desert whereas what is written earlier refers to what transpired in the first year of the Israelites' wanderings. Perhaps the word על דבר is meant to alert us that what they did with Bileam would have sufficed to exclude them forever as members of the Jewish people. The word קדמו means they should have come forward on their own account offering bread and water as gifts. This would have been only small recompense for all which our forefather Abraham had done for them. Instead of repaying good with good they had repaid good with evil. The plain meaning of the words לא קדמו אתכם is that they did nothing for your benefit.
Ramban
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.226Above 2:28-29. [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 scholars227Mentioned so in Ibn Ezra (above, 2:29). 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,228Judges 11:18. 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?229Verse 8. And Rabbi Abraham ibn Ezra stated227Mentioned so in Ibn Ezra (above, 2:29). that “the expression as the children of Esau … and the Moabites did unto me230Above, 2:29. refers to the verse, Let me pass through thy land; I will go along by the highway,231Ibid., 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’232Numbers 20:18. [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,”233Ibid., 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.234Ibid., 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 Edom235Ibid., 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 came to Kadesh; then Israel sent messengers unto the king of Edom, saying: Let me, I pray thee, pass through thy land; but the king of Edom hearkened not. And in like manner he sent unto the king of Moab; but he would not; and Israel abode in Kadesh. Then he walked through the wilderness, and compassed the land of Edom, and the land of Moab, and came by the east side of the land of Moab, and they pitched on the other side of Arnon, but they came not within the border of Moab.236Judges 11:16-18. Thus it is clearly explained that they did not come into the land of Edom or the land of Moab at all. Had they come there, the Edomites and Moabites would have sold them bread and water, for it is not customary for one who allows an army to pass through a land not to sell them bread and water.
It appears to me that Scripture banned these two brothers [Ammon and Moab, sons of Lot — from the congregation of Israel] because they were the beneficiaries of the lovingkindness of Abraham who saved their father and mother from the sword and captivity237See Genesis 14:16. and, by virtue of Abraham’s merit, G-d sent them out of the midst of the overthrow [of Sodom]238Ibid., 19:29. — hence they were obligated to do good to Israel and instead they did them evil. One of them [the Moabites] hired Balaam the son of Beor against Israel, and one [the Ammonites] did not meet them with bread and water as they approached their territory, as it is written, Thou art this day to pass over the border of Moab, even Ar; and thou comest nigh over against the children of Ammon.239Above, 2:18-19. Now Scripture warned the Israelites [concerning the children of Ammon] harass them not, nor contend with them.240Ibid., Verse 19. And yet the Ammonites did not meet them at all [with bread and water], for otherwise Scripture would have stated, “As the children of Esau, and the Moabites, ‘and the Ammonites’ did unto me,” but the verse230Above, 2:29. does not mention Ammon because they did not meet them. Thus Ammon acted more wickedly than all of them, for the children of Esau and the Moabites, when they knew that the Israelites were warned against contending with them in battle, brought bread and water out of their border, but Ammon did not wish to do so. This is the meaning of the phrase, because they met you not, that they did not come forth toward them with bread and water as the others did. Therefore Scripture mentioned an Ammonite first [An Ammonite or a Moabite shall not enter into the assembly of the Eternal],241Verse 4. and it cited his sin first, because they met you not with bread and water, and then it mentioned a Moabite and his sin [and because they hired against thee Balaam].
Now our Rabbis interpreted:242Yebamoth 76b. “An Ammonite, but not an Ammonitess [if she is converted to Judaism she may be married to an Israelite]. A Moabite, but not a Moabitess, because it is customary for a man to meet [a passing camp with bread and water] but it is not customary for a woman to meet,” to bring forth food outside of the border of the land. And so the Rabbis also mentioned in the Yerushalmi243Yerushalmi Yebamoth VIII, 3. and in the Scroll of Ruth Rabbathi:244Ruth Rabbathi 4:8. “It is customary for a man to hire but it is not customary for a woman to hire.”245Hence the Ammorite and Moabite women were not considered as having partaken in the sins of the men and, therefore, the women were excluded from the prohibition. When Ruth the Moabitess adopted the faith of Israel, therefore, Boaz was permitted to marry her.

היצא מגבל האמרי [ARNON WHICH IS IN THE WILDERNESS] THAT COMETH OUT OF THE BOUNDARY OF THE AMORITES — a strip of land jutted out from the territory of the Amorites — it belonged to the Amorites — and entered into the territory of Moab extending unto the Arnon which is the boundary of Moab. It was there that the Israelites encamped and thus they did not pass into the territory of Moab, כי ארנון גבול מואב, FOR ARNON IS THE BOUNDARY OF MOAB, and they did not grant them permission to pass through their land. And although Moses did not state this plainly, Jephtha plainly stated it], as Jephtha said, (Judges 11:17) "And in like manner he sent unto the king of Moab, out he would not permit him to pass through his territory”. Moses, however, made an allusion to it when he stated, (Deuteronomy 2:29) “As the children of Esau that dwell in Seir, and the Moabites that dwell in Ar, did unto me”. What was the case with these (the children of Esau)? They did not permit them to pass through their land, but they made them travel right round it! Similarly, too, Moab did!
Rashi
And he refused. Moshe alludes to this in the Torah, "As perpetrated against me by the Bnei Eisov residing at Sair, and the Moavites residing at Ar."2Devarim, 2:29. Just as Edom refused them permission to pass, so did Moav refuse them permission to pass.
