144,000

Rev. 14:1-5 (ESV)
Then I looked, and behold, on Mount Zion stood the Lamb, and with him 144,000 who had his name and his Father's name written on their foreheads. [2] And I heard a voice from heaven like the roar of many waters and like the sound of loud thunder. The voice I heard was like the sound of harpists playing on their harps, [3] and they were singing a new song before the throne and before the four living creatures and before the elders. No one could learn that song except the 144,000 who had been redeemed from the earth. [4] It is these who have not defiled themselves with women, for they are virgins. It is these who follow the Lamb wherever he goes. These have been redeemed from mankind as firstfruits for God and the Lamb, [5] and in their mouth no lie was found, for they are blameless.

Just when it look the most dire, The two beasts unleashing their campaign on earth, you see the lamb and the 144,000 with him. His host the most perfect military, the church militant stands behind him. 144,000 that is the church militant, it is 12,000 times 12, twelve thousand from each of the twelve tibes of Israel. The number is figurative. It is to convey the totality of all of Israel, God’s people on earth. They find their victory in the lamb to whom they sing. The dragons will not have victory over them, because the lamb has already conquered them.
