ISB ~ Jude 1 v9

archangel Michael:The guardian angel of the People of God (Dan 10:21; 12:1). He leads the angelic armies of heaven into war against Satan and his hosts (Rev 12:7-9).

The Lord rebuke you:The dispute between Michael and the devil derives from a Jewish legend called The Assumption of Moses. The extant version of this work lacks a conclusion, stopping before the death of Moses, but several Church Fathers tell us that the story comes from this source. Note that when biblical writers quote from non-biblical works, they do not thereby endorse these writings as uniformly acceptable; nor are citations from them an implicit claim that such texts are on a par with inspired Scripture. Reference to noncanonical literature is sometimes used for the sake of illustration or to help communicate truth in terms that are familiar to the original readers (cf. Acts 17:28; 1 Cor 15:33; Tit 1:12).

• A similar rebuke was uttered against Satan in Zech 3:2.
