'Multitude' in the Bible

After this I beheld, and, lo, a great multitude, which no man could number, of all nations, and kindreds, and people, and tongues, stood before the throne, and before the Lamb, clothed with white robes, and palms in their hands;

In this case wisdom is needed: Let the person who has understanding calculate the total of the beast, since it is a human multitude, and the sum of the multitude is 600, 60 and six.

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,

And I heard as it were the voice of a great multitude, and as the voice of many waters, and as the voice of mighty thunderings, saying, Alleluia: for the Lord God omnipotent reigneth.
