신명기 32:10 주석: Rashi, Ramban, Sforno & Or HaChaim

ימצאהו בארץ מדבר HE FOUND HIM IN A DESERT LAND — for them (Jacob’s sons) he found to be faithful to Him in the desert land, when they accepted His Torah, His sovereignty and His yoke, something that Ishmael and Esau had refused to do, as it is said, (Deuteronomy 33:2) “And He shone from the Seir (Esau) unto them, He appeared from Mount Paran (Ishmael)” (cf. Rashi on that verse).

The expression [He kept him] as the apple of His eye⁴⁴Verse 10. alludes to watchfulness, the verse stating that G-d watched over him as He would shield “His own eye.” Or it may be that the word “man” is missing here: He watched over him as a man shields the apple of his eye, for generally [where there is no specific reference to the contrary, it is assumed that] Scripture speaks of man. There are many similar verses.

ימצאהו בארץ מדבר, in the desert He found that the heart of this nation which He considered His only share among mankind was pure and loyal, as testified to in Jeremiah 2,2 “you followed Me into the desert.”
