Deuteronomy 22:8-10

8“When you build a new house, you must build a railing around the edge of its flat roof. That way you will not be considered guilty of murder if someone falls from the roof.

9“You must not plant any other crop between the rows of your vineyard. If you do, you are forbidden to use either the grapes from the vineyard or the other crop.

10“You must not plow with an ox and a donkey harnessed together.
