Deuteronomy 22:9-12 - Illustrations Of The Principle Of Purity

9 You shall not sow your vineyard with two kinds of seed, lest the whole fruit be forfeited, the seed which you have sown, and the increase of the vineyard. 10 You shall not plow with an ox and a donkey together. 11 You shall not wear a mixed stuff, wool and linen together. 12 You shall make yourselves fringes on the four borders of your cloak, with which you cover yourself.
