55Then John saw four angels waiting. They were at the four corners of the earth and they held back the wind so the winds could not blow across the earth or the sea.

     Then another angel came from the east and shouted to the four angels, who had the authority to harm the land and sea. "Wait! Don't damage the earth or the trees or the seas before we place the seal of the Almighty God on the foreheads of His faithful followers from Israel."
       

 They are the ones that received His Son and are born of the Spirit of God. There will be 144,000; 12,000 from the 12 tribes of Israel.
