Over all the Nine Ranks, the Lord put the Holy Leader Michael (his name in translation from the Hebrew means “who is like unto God”) — a faithful servitor of God, wherein he hurled down from Heaven the arrogantly proud day-star Lucifer together with the other fallen spirits. And to the remaining Angelic powers he cried out: “Let us attend! Let us stand aright before our Creator and not ponder that which is displeasing unto God!” According to Church tradition, in the church service to the Archistrategos Michael concerning him, he participated in many other Old Testament events. During the time of the Exodus of the Israelites from Egypt he went before them in the form of a pillar of cloud by day and a pillar of fire by night. Through him the power of the Lord was made manifest, annihilating the Egyptians and Pharaoh who were in pursuit of the Israelites. The Archangel Michael defended Israel in all its misfortunes.
He appeared to Jesus Son of Navin (Joshua) and revealed the will of the Lord at the taking of Jericho (Nav / Josh 5:13-16). The power of the great Archistrategos of God was manifest in the annihilation of the 185 thousand soldiers of the Assyrian emperor Sennacherib (4  Kings 19:35); also in the smiting of the impious leader Antiochos Illiodoros; and in the protecting from fire of the Three Holy Youths — Ananias, Azarias and Misail, thrown into the fiery furnace for their refusal to worship an idol (Dan 3:22-25).
Through the will of God, the Archistrategos Michael transported the Prophet Avvakum (Habbakuk) from Judea to Babylon, so as to give food to Daniel, locked up in a lions’ den (Kondak of Akathist, 8).
The Archangel Michael prevented the devil from displaying the body of the holy Prophet Moses to the Jews for idolisation (Jude 1:9).
The holy Archangel Michael showed his power when he miraculously saved a lad, cast by robbers into the sea with a stone about his neck at the shores of Athos [Athos Paterikon].
