'Undergarments' in the Bible

Make them linen undergarments to cover their naked bodies; they must extend from the waist to the thighs.

They also made the turban and the ornate headbands of fine linen, the undergarments,

The priest is to put on his linen robe and linen undergarments. He is to remove the ashes of the burnt offering the fire has consumed on the altar, and place them beside the altar.

He is to wear a holy linen tunic, and linen undergarments are to be on his body. He must tie a linen sash around him and wrap his head with a linen turban. These are holy garments; he must bathe his body with water before he wears them.

They must wear linen turbans on their heads and linen undergarments around their waists. They are not to put on anything that makes them sweat.
