Revelation 7:1-6

1 After the vision of these things I saw four angels standing at the four corners of the earth. The angels were holding the four winds of the earth to keep them from blowing on the land or on the sea or on any tree.
2 Then I saw another angel coming up from the east who had the seal of the living God. And he called out in a loud voice to the four angels to whom God had given power to harm the earth and the sea.
3 He said to them, "Do not harm the land or the sea or the trees until we mark with a sign the foreheads of the people who serve our God."
4 Then I heard how many people were marked with the sign. There were one hundred forty-four thousand from every tribe of the people of Israel.
5 From the tribe of Judah twelve thousand were marked with the sign, from the tribe of Reuben twelve thousand, from the tribe of Gad twelve thousand,
6 from the tribe of Asher twelve thousand, from the tribe of Naphtali twelve thousand, from the tribe of Manasseh twelve thousand,
