Deuteronomy 22:9-12 - Illustrations Of The Principle Of Purity
9 Thou shall not sow thy vineyard with two kinds of seed, lest the whole fruit be forfeited: the seed which thou have sown, and the increase of the vineyard. 10 Thou shall not plow with an ox and a donkey together. 11 Thou shall not wear a mingled stuff, wool and linen together. 12 Thou shall make for thee fringes upon the four borders of thy clothing, with which thou cover thyself.
