Revelation 7:1-8
After this I saw four angels standing at the four corners of the earth, holding back the four winds of the earth, that no wind might blow on earth or sea or against any tree.
Then I saw another angel ascend from the rising of the sun, with the seal of the living God, and he called with a loud voice to the four angels who had been given power to harm earth and sea, saying, "Do not harm the earth or the sea or the trees, till we have sealed the servants of our God upon their foreheads."
And I heard the number of the sealed, a hundred and forty-four thousand sealed, out of every tribe of the sons of Israel, twelve thousand sealed out of the tribe of Judah, twelve thousand of the tribe of Reuben, twelve thousand of the tribe of Gad, twelve thousand of the tribe of Asher, twelve thousand of the tribe of Naph'tali, twelve thousand of the tribe of Manas'seh, twelve thousand of the tribe of Simeon, twelve thousand of the tribe of Levi, twelve thousand of the tribe of Is'sachar, twelve thousand of the tribe of Zeb'ulun, twelve thousand of the tribe of Joseph, twelve thousand sealed out of the tribe of Benjamin.
