Seal of God - God is marking on our foreheads.

Revelation 9:1The fifth angel sounded his trumpet, and I saw a star that had fallen from the sky to the earth. The star was given the key to the shaft of the Abyss. 4 They were told not to harm the grass of the earth or any plant or tree, but only those people who did not have the seal of God on their foreheads.

Revelation 7:3 “Do not harm the land or the sea or the trees until we put a seal on the foreheads of the servants of our God.”

Matthew 4:12 When Jesus heard that John had been put in prison, he withdrew to Galilee. 13 Leaving Nazareth, he went and lived in Capernaum, which was by the lake in the area of Zebulun and Naphtali— 14 to fulfil what was said through the prophet Isaiah:

15 “Land of Zebulun and land of Naphtali,
the Way of the Sea, beyond the Jordan,
Galilee of the Gentiles—
16 the people living in darkness
have seen a great light;
on those living in the land of the shadow of death
a light has dawned.”

17 From that time on Jesus began to preach, “Repent, for the kingdom of heaven has come near.”
