While Satan was urging his accusations, holy angels, unseen, were passing to and fro, placing upon them the seal of the living God. (Mar 213.7) MC VC

“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, saying, Hurt not the earth, neither the sea, nor the trees, till we have sealed the servants of our God in their foreheads.” Revelation 7:2, 3. (Mar 243.1) MC VC
