Do not plant your vineyard with two types of seed; if you do, the entire harvest will be defiled—both the crop you plant and the fruit of your vineyard. Do not plow with an ox and a donkey yoked together. Do not wear clothes of wool and linen woven together.
"You are to construct the tabernacle itself with ten curtains of finely spun linen, each with blue, purple, and scarlet yarn, and cherubim skillfully worked into them.
Significance
Exodus 26:1 prescribes tabernacle curtains from "finely twisted linen and blue, purple, and scarlet yarn"—a deliberate mixing of materials. Deuteronomy 22:9-11 prohibits mixing seeds, yoking different animals, and wearing mixed wool-linen garments (שַׁעַטְנֵז, sha'atnez). The tabernacle's prescribed combination of materials forbidden in everyday life reveals a holiness-boundary principle: material combinations reserved for God's dwelling symbolize the unique intersection of heaven and earth at the sanctuary. The daily prohibition preserves the sacred-common distinction by ensuring ordinary Israelites do not replicate in their clothing what belongs exclusively to the tabernacle's sacred fabric.
