Deuteronomy 22:8-10

8If you build a new house, you must make a wall around the edge of the flat roof. Then if someone falls off the roof and dies, you will not be guilty for his death.

9You must not plant any other crops between the vines in your vineyard. If you do that, none of the food or the grapes will belong to you.

10You must not tie an ox and a donkey together to pull a plough.
