Revelation 7:2-3

Then I saw another angel ascending from the east, having the seal of the living God.  And he cried with a loud voice to the four angels to whom it was granted to harm the earth and the sea, saying, “Do not harm the earth, the sea, or the trees till we have sealed the servants of our God on their foreheads.”

Psalm 72:8  He shall have dominion also from sea to sea, and from the River to the ends of the earth.

2 Timothy 2:19  Nevertheless, the solid foundation of God stands, having this seal:  “The Lord knows those who are His, and “Let everyone who names the name of Christ depart from iniquity.”
