פירוש על דברים 32:38

אשר חלב זבחימו THE FAT OF WHOSE SACRIFICES THEY, i.e. these gods — used to eat, which they offered to them, and which used to drink יין נסיכם THE WINE OF THEIR DRINK OFFERING.

יקומו ויעזרכם, "Let them arise and help you!" There are two kinds of idolatry and idolators. 1) Someone is wholly committed to serve idols for their own sake. 2) Someone who only serves idols for self-serving purposes, i.e. in order to manipulate the deity for his own purpose. G'd forbade both kinds of idolatry in Exodus 20,4. Concerning the person who only goes through the motions of serving an idol for what he expects to get out of it, G'd said here: "let the deity arise and help you, i.e. you will be sorely disappointed." Concerning the other type of idolator G'd says sarcastically: יהי עליכם סתרה, "let them be a hide-out for you!"

אשר חלב זבחימו יאכלו, the deities whom the Israelites worshipped and to whom they presented their offerings.
