'Foreheads' in the Bible

"Injure neither land nor sea nor trees," he said, "until we have sealed the bondservants of our God upon their foreheads."

And they were forbidden to injure the herbage of the earth, or any green thing, or any tree. They were only to injure human beings--those who have not the seal of God on their foreheads.

And he causes all, small and great, rich and poor, free men and slaves, to have stamped upon them a mark on their right hands or on their foreheads,

Then I looked, and I saw the Lamb standing upon Mount Zion, and with Him 144,000 people, having His name and His Father's name written on their foreheads.

And I saw thrones, and some who were seated on them, to whom judgment was entrusted. And I saw the souls of those who had been beheaded on account of the testimony that they had borne to Jesus and on account of God's Message, and also the souls of those who had not worshipped the Wild Beast or his statue, nor received his mark on their foreheads or on their hands; and they came to Life and were kings with Christ for a thousand years.

and His name will be on their foreheads.
