Deuteronomy 22:9-12 - Illustrations Of The Principle Of Purity
9 You must not plant your vineyard with two kinds of seed; otherwise the entire yield, both of the seed you plant and the produce of the vineyard, will be defiled. 10 You must not plow with an ox and a donkey harnessed together. 11 You must not wear clothing made with wool and linen meshed together. 12 You shall make yourselves tassels for the four corners of the clothing you wear.
