Deuteronomy 22:9-12 - Illustrations Of The Principle Of Purity
9 Thou shalt not sow thy vineyard with divers seeds: lest the fruit of thy seed which thou hast sown, and the fruit of thy vineyard, should be defiled. 10 Thou shalt not plow with an ox and an ass together. 11 Thou shalt not wear a garment of divers sorts, as of woolen and linen together. 12 Thou shalt make thee fringes upon the four quarters of thy vesture, with which thou coverest thyself.
