'Forehead' in the Bible

Let it serve as a sign for you on your hand and as a reminder on your forehead, so that the Lord’s instruction may be in your mouth; for the Lord brought you out of Egypt with a strong hand.

So let it be a sign on your hand and a symbol on your forehead, for the Lord brought us out of Egypt by the strength of His hand.”

It will be on Aaron’s forehead so that Aaron may bear the guilt connected with the holy offerings that the Israelites consecrate as all their holy gifts. It is always to be on his forehead, so that they may find acceptance with the Lord.
