'Foreheads' in the Bible

“You are the sons of the Lord your God; you shall not cut yourselves nor shave your forehead for the sake of the dead,

Behold, I have made your face as hard as their faces and your forehead as hard as their foreheads.

The Lord said to him, “Go through the midst of the city, throughout all of Jerusalem, and put a mark on the foreheads of the men who sigh [in distress] and grieve over all the repulsive acts which are being committed in it.”

Utterly slay old men, young men, maidens, little children, and women; but do not touch or go near anyone on whom is the mark. Begin at My sanctuary.” So they began with the old men who were in front of the temple [who did not have the Lord’s mark on their foreheads].

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.”

They were told not to hurt the grass of the earth, nor any green thing, nor any tree, but [to hurt] only the people who do not have the seal (mark of ownership, protection) of God on their foreheads.

Also he compels all, the small and the great, and the rich and the poor, and the free men and the slaves, to be given a mark on their right hand or on their forehead [signifying allegiance to the beast],

Then I looked, and this is what I saw: the Lamb stood [firmly established] on Mount Zion, and with Him a hundred and forty-four thousand who had His name and His Father’s name inscribed on their foreheads [signifying God’s own possession].

And then I saw thrones, and sitting on them were those to whom judgment [that is, the authority to act as judges] was given. And I saw the souls of those who had been beheaded because of their testimony of Jesus and because of the word of God, and those who had refused to worship the beast or his image, and had not accepted his mark on their forehead and on their hand; and they came to life and reigned with Christ for a thousand years.

they will [be privileged to] see His face, and His name will be on their foreheads.
