Revelation 7:2-8

2Then I saw another angel coming up from the rising of the sun, holding the seal of the living God; and with a loud voice he called out to the four angels to whom it was granted [to have authority and power] to harm the earth and the sea,

3saying, “Do not harm the earth nor the sea nor the trees until we seal (mark) the bond-servants of our God on their foreheads.”

4And I heard how many were sealed, a hundred and forty-four thousand; [twelve thousand] sealed from every tribe of the sons of Israel:

5Twelve thousand were sealed from the tribe of Judah, twelve thousand from the tribe of Reuben, twelve thousand from the tribe of Gad,

6twelve thousand from the tribe of Asher, twelve thousand from the tribe of Naphtali, twelve thousand from the tribe of Manasseh,

7twelve thousand from the tribe of Simeon, twelve thousand from the tribe of Levi, twelve thousand from the tribe of Issachar,

8twelve thousand from the tribe of Zebulun, twelve thousand from the tribe of Joseph, and twelve thousand from the tribe of Benjamin were sealed (marked, redeemed, protected).
