³⁷ You should fasten it on the turban with a blue cord. It should be on the front of the turban. ³⁸ It will be on Aaron’s forehead, and Aaron will take on himself any guilt connected with the holy offerings that the Israelites give as their sacred donations. It will always be on his forehead so that the people may be remembered favorably in the Lord’s presence.
