Exodus 28:37-39

New Century Version

³⁷ Use blue ribbon to tie it to the turban; put it on the front of the turban. ³⁸ Aaron must wear this on his forehead. In this way, he will be blamed if anything is wrong with the gifts of the Israelites. Aaron must always wear this on his head so the Lord will accept the gifts of the people.

³⁹ “Make the woven inner robe of fine linen, and make the turban of fine linen also. Make the cloth belt with designs sewn on it.
