'Gird' in the Bible

Take the garments and clothe Aaron with the tunic, the robe of the ephod, the ephod, and the breast piece, and then gird him with the skillfully woven band of the ephod.

You are to gird Aaron and his sons with sashes and tie headdresses on them. The priesthood is to belong to them by perpetual ordinance, and you are to ordain Aaron and his sons.
