'Crowd' in the Bible

After these things I saw, and lo, a great crowd, which no one could number, out of every nation and tribes and peoples and tongues, standing before the throne, and before the Lamb, clothed with white robes, and palm branches in their hands.

And I heard as a voice of a great crowd, and as a voice of many waters, and as a voice of strong thunders, saying, Hallelujah, for the Lord our God the Almighty has taken to himself kingly power.
