Revelation 7:1-3

After this I saw four angels stationed at the four corners of the earth, holding back the four winds of the earth so that no wind would blow on the earth or on the sea or on any tree. [Zech 6:5] Then 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, saying, “Do not harm the earth nor the sea nor the trees until we seal (mark) the bond-servants of our God on their foreheads.” [Ezek 9:4]
