Ki Tetze
21:10 If you go out to war against your enemy and the L-rd your
G-d delivers him into your hand, and you capture its
captivity,
If you go out to war – This [ 4
‘If’] teaches us that Scripture is here
speaking of a permitted war “
and you capture its captivity – to include Canaanites from outside Eretz
Yisrael, who, if they repent, may be accepted (Sotah 35b).69

23:8 You shall not despise an Edomi, for he is your brother.
You shall not despise an Egyptian, for you were a stranger
in his land.
You shall not despise an Egyptian – R. Yossi opened [his discourse] in
honor of the host, expounding: Now if of the Egyptians, who befriended
Israel for mercenary motives only, as it is written (Genesis 47:6): “and if
you know of capable men among them, then make them overseers of my
cattle” —Scripture writes: “You shall not despise an Egyptian, for you
were a stranger in his land” — then one who is host to a Torah scholar,
and feeds him, and gives him to drink, and treats him of his possessions
— how much more so! (Berachoth 63b).־ “
for you were a stranger ־ Rava asked Rabbah b. Mari: Whence is
derived the folk-expression: “Cast no aspersions on the well from which
you have drunk”? From: “You shall not despise an Egyptian, for you
were a stranger in his land” (Bava Kamma 92b).34
