'Forehead' in the Bible

It will be a sign for you on your hand and a memorial on your forehead, so that the law of the Lord may be in your mouth, for with a mighty hand the Lord brought you out of Egypt.

It will be for a sign on your hand and for frontlets on your forehead, for with a mighty hand the Lord brought us out of Egypt."

It will be on Aaron's forehead, and Aaron will bear the iniquity of the holy things, which the Israelites are to sanctify by all their holy gifts; it will always be on his forehead, for their acceptance before the Lord.
