Judges 1:9

The archangel; the word archangel means a chief angel, or ruler of angels. the inspired writers of the New Testament occasionally refer, as is done here and in verse Judges 1:14, to events not recorded in the Old Testament, but handed down in tradition. Compare 2 Timothy 3:8. We know nothing more of the event here referred to than what Jude has given us.

Durst not; not because he feared the devil, but because he feared God, and feared to commit sin by using reproachful language.

Rebuke thee; restrain thy rage, control, and punish thee. Holy beings will not use reproachful epithets even towards the devil, much less towards men, especially magistrates, and those whom God requires us to honor. Those who delight in such language show themselves to be servants of the evil one.
