Numbers
Speak to Bnei Yisroel and tell them to make for themselves, tzizis-fringes on the corners of their garments—throughout their generations; and they will place with the fringes of each corner a thread of blue.
Leviticus
Keep My statutes; Do not cross-breed your animals with different species. Do not sow your field with a mixture of different seeds. A garment that contains shatnez [a forbidden mixture of linen and wool] you shall not wear.
