Michael is an ARCH ANGEL
[ 16 because the Lord himself will descend from heaven with a commanding call, with an archangel’s voice and with God’s trumpet, and those who are dead in union with Christ will rise first. 17 Afterward we the living who are surviving will, together with them, be caught away in clouds to meet the Lord in the air; and thus we will always be with the Lord.]
[ 30 ... they will see the Son of man coming on the clouds of heaven with power and great glory. 31 And he will send out his angels with a great trumpet sound, and they will gather his chosen ones together from the four winds, from one extremity of the heavens to their other extremity.]

[2 the sons of the true God began to notice that the daughters of men were beautiful. So they began taking as wives all whom they chose.]
[6 Now the day came when the sons of the true God entered to take their station before Jehovah, and Satan also entered among them.]
[ 7 When the morning stars joyfully cried out together, And all the sons of God began shouting in applause?]
