You can sell us food to eat and water to drink in exchange for silver. Only let us pass through on foot,
God having tried the self-denial of his people in forbidding them to meddle with the Moabites and Ammonites, and they having quietly passed by those rich countries, and, though superior in number, not made any attack upon them, here he recompenses them for their obedience by giving them possession of the country of Sihon king of the Amorites.
Commenting on Deuteronomy 2:24-37
Thou shalt sell me meat for money, that I may eat,.... If they thought fit to have provision of them, they desired no other but to pay for it: and give me water for money, that I may drink; see Deu 2:6, only I will pass through on my feet; for they were all footmen, Num 11:21, of the phrase; see Gill on Num 20:19.
Deu 2:26-30 If Moses, notwithstanding this, sent messengers to king Sihon with words of peace (Deu 2:26.; cf. Num 21:21.), this was done to show the king of the Amorites, that it was through his own fault that his kingdom and lands and life were lost.
