“He shall therefore burn that garment in which is the plague, whether warp or woof, in wool or in linen, or anything of leather, for it is an active leprosy; the garment shall be burned in the fire” (Leviticus 13:52)
The warp and woof:
Technically defined (textile discourse): the warp is the yarn that runs up and down. They are held stationary in a loom. The woof runs right to left, left to right, and is drawn through the warp.
More generally, the “warp and woof” identities the foundation, the base, or the whole system. It is that which holds together all the pieces, making fragments united as one whole.
In Leviticus, “whether warp or woof” denotes any thread containing leprosy that is unclean and deserving of fire.
“But if the priest examines it, and indeed the plague has not spread in the garment, either in the warp or in the woof, or in anything made of leather, then the priest shall command that they wash the thing in which is the plague; and he shall isolate it another seven days.” (Leviticus 13:53-54)
The law regarding leprous garments holds meaning for Christians today to the extent that the Levitical priests atoning for an individual before the Lord foreshadows the death, burial, and resurrection of Jesus Christ who cleansed whosoever believes on Him, whosoever believes in his heart and professes His name. Jesus cleansed all sinful plagues past, present, and future.
Dead in our sins and trespasses, we were leperous; being “as one dead, whose flesh is half consumed” (Leviticus 12:12). If dead, we cannot raise ourselves, “And such were some of you: but ye are washed, but ye are sanctified, but ye are justified in the name of the Lord Jesus, and by the Spirit of our God” (1 Corinthians 6:11).
Cleansed in warp and woof: You are being sanctified in your mind, body, and soul.
