QUESTIONS ON RASHI
Rashi writes 'which I did not command you to worship.' Is it not obvious that Hashem did not command us to serve Avodah-Zarah?
Rabeinu Bachye #1: We might otherwise have thought that it is comparable to someone who pays homage to the servant of the king, which is akin to paying homage to the king himself. 1
Rabeinu Bachye #2 (according to Kabalah): Although Hashem commanded us to bring the Korban Tamid "One lamb in the morning and a second lamb in the afternoon" 2 corresponding to the Midas ha'Yom and the Midas ha'Laylah, respectively, He did not command us to worship the sun and the moon.
