Deuteronomy 22:11

A garment... of woollen and linen together. — In Ezekiel 44:17, the priests are altogether forbidden the use of woollen garments during their ministry. “The fine linen is the righteousness of saints” (Revelation 19:8), literally, their requirements. That is what they need. But it is said of the priests in Ezekiel, “They shall not gird themselves with anything that causeth sweat: That which cometh out of the man defileth him.” Again, in God’s dwelling-place, the interior or mishkân, the tabernacle where He abode, was of fine linen. The outer tent and coverings were of hair and skin and wool. The tabernacle where He dwells, and the earthly house of the tabernacle, must be kept distinct, while His tabernacle “remaineth among us in the midst of our uncleanness.” (See Leviticus 16:16).
