“They also made the tunics, woven of fine linen, for Aaron and his sons. They made the turban of fine linen, and the headdresses of fine linen, and the linen undergarments of fine twined linen. They made the sash of fine twined linen and of blue, purple, and crimson yarns, embroidered with needlework, as Yahweh had commanded Moses.”
Following as Yahweh had commanded Moses in chapter 28 they also made the tunics for Aaron and his sons. Besides the linen tunics, they also made the linen turban, the headdresses, the linen undergarments, and the linen sashes.
