Mat 24:14 And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come. Rev 7:2 And 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 given to hurt the earth and the sea, Rev 7:3 Saying, Hurt not the earth, neither the sea, nor the trees, till we have sealed the servants of our God in their foreheads. Rev 7:4 And I heard the number of them which were sealed: [and there were] sealed an hundred [and] forty [and] four thousand of all the tribes of the children of Israel.
