'Head dress' in the Bible

This is what they are to make: a priest's bag, an ephod, and a robe, and a coat of coloured needlework, a head-dress, and a linen band; they are to make holy robes for Aaron your brother and for his sons, so that they may do the work of priests for me.

Put a blue cord on it and put it on the front of the twisted head-dress:

The coat is to be made of the best linen, worked in squares; and you are to make a head-dress of linen, and a linen band worked in needlework.

And let the head-dress be placed on his head and the holy crown on the head-dress.

And the twisted head-dress for Aaron, and beautiful head-dresses of linen, and linen trousers,

It was fixed to the head-dress by a blue cord, as the Lord had given orders to Moses.
