Rav Nachman taught that the angel of whom God spoke in was Metatron (). Rav Nahman warned that one who is as skilled in refuting heretics as Rav Idit should do so, but others should not. Once a heretic asked Rav Idit why says, "And to Moses He said, 'Come up to the Lord,'" when surely God should have said, "Come up to Me." Rav Idit replied that it was the angel Metatron who said that, and that Metatron's name is similar to that of his Master (and indeed the gematria (numerical value of the Hebrew letters) of Metatron () equals that of Shadai (), God's name in and elsewhere) for says, "for my name is in him." But if so, the heretic retorted, we should worship Metatron. Rav Idit replied that also says, "Be not rebellious against him," by which God meant, "Do not exchange Me for him" (as the word for "rebel," (, "tameir") derives from the same root as the word "exchange"). The heretic then asked why then says, "he will not pardon your transgression." Rav Idit answered that indeed Metatron has no authority to forgive sins, and the Israelites would not accept him even as a messenger, for reports that Moses told God, "If Your Presence does not go with me, do not carry us up from here."
