The word "archangel" comes from the Greek ἀρχάγγελος (archangělǒs), meaning chief angel, a translation of the Hebrew רב־מלאך (rav-mal'ákh). It derives from the Greek archō, meaning to be first in rank or power; and angělǒs which means messenger or envoy. The word is only used twice in the New Testament: 1 Thessalonians 4:16 and Jude 1:9. Only Archangels Gabriel and Michael are mentioned by name in the New Testament.
