Commentaire sur Le Deutéronome 7:2

ולא תחנם means, THOU SHALT NOT ASCRIBE GRACE (חן) TO THEM: it is forbidden to a person to say “How beautiful is this heathen”. Another explanation: thou shalt not grant them a חניה, an encampment (a settlement) in the land (Avodah Zarah 20a).

ולא תחנם, “and you are not to show them any favor.” The word תחנם has been explained in many different ways. It may mean חן, grace, charm; it may mean חנינה, compassion, pardon. Clearly, the plain meaning is from חנינה, compassion, reprieve, and tells us that we must not indulge our feelings of compassion vis-a-vis these people. It is as if the Torah had written לא תחון אותם, “do not be charmed by them”. According to the Talmud in Avodah Zarah 20 it is forbidden to even comment on the aesthetic beauty of artifacts designed in honor of idols. One must not even admire the physical features of a handsome Gentile or a beautiful Gentile woman. The Talmud suggests that this is part of the word לא תחנם when we read the letter ח as if it had the vowel chirik underneath it. They also understand the expression as meaning that we must not grant these people חניה “parking,” i.e. temporary residence status and that it is forbidden to sell any land to Gentiles in the land of Israel. The Torah spelled out the reason when it said “so that they will not lead you into sin.” You must also not give them any gift, including land, the letters in the word תחנם being read with the vowel pattern patach, sheva, patach, i.e. tachnam. In fact, the word lends itself to still further permutations by changing the vowel pattern. Basically, the sages demonstrate the power of the written Torah, which, because it does not have vowels or other signs such as commas and period signs, is capable of being interpreted in so many different ways. Changing the vowel pattern can give a single word many different meanings. Having appreciated this you will understand even better the power inherent in the names of G’d which lend themselves to so many permutations, i.e. different emphasis of the basic concept of Hashem. I have elaborated on this already in my comments on Numbers 11,15.

Do not hold them in esteem, etc. This interpretation is problematic, for it should say תחנן with the letter nun, which is the term for esteem. Alternatively, it should say תחונם, spelled with a vov. Therefore Rashi says, “Another interpretation: Do not give them an encampment.” In other words: Even if you do not make a treaty, but think to [let them live with you and] tax them. Therefore it says not to give them any settlement at all in the Land. The second explanation is problematic, for then the verse should only state not to give them any settlement in the Land (לא תחנם), and all the more so [we would know that] it is forbidden to make a treaty with them. Therefore the first explanation is also needed.
