⁴⁰ For Aaron’s sons you shall make long and sleeved tunics and belts or sashes and caps, for glory and honor and beauty.

⁴¹ And you shall put them on Aaron your brother and his sons with him, and shall anoint them and ordain and sanctify them [set them apart for God], that they may serve Me as priests.

⁴² You shall make for them [white] linen trunks to cover their naked flesh, reaching from the waist to the thighs.
