In Sanhedrin 38b one of the tells Rabbi Idith that Metatron should be worshiped because he has a name like his master. Rabbi Idith uses the same passage Exodus 23:21 to show that Metatron was an angel and not a deity and thus should not be worshiped. Furthermore, as an angel, Metatron has no power to pardon transgressions nor was he to be received even as a messenger of forgiveness.Sanhedrin 38a
