'Multitude' in the Bible

After this I looked, and there was a vast multitude from every nation, tribe, people, and language, which no one could number, standing before the throne and before the Lamb. They were robed in white with palm branches in their hands.

After this I heard something like the loud voice of a vast multitude in heaven, saying:Hallelujah!Salvation, glory, and power belong to our God,

Then I heard something like the voice of a vast multitude, like the sound of cascading waters, and like the rumbling of loud thunder, saying:Hallelujah, because our Lord God, the Almighty,has begun to reign!
