“Indeed, ask about the earlier days that preceded you, from the day God created man on the earth and from one end of the heavens to the other: Has anything like this great event ever happened, or has anything like it been heard of?

And let the overseers say to the people, If there is any man who has made for himself a new house and has not gone into it, let him go back to his house, so that in the event of his death in the fight, another may not take his house for himself.

Or if any man has made a vine-garden without taking the first-fruits of it, let him go back to his house, so that in the event of his death in the fight, another may not be the first to make use of the fruit.

Or if any man is newly married and has had no sex relations with his wife, let him go back to his house, so that in the event of his death in the fight, another man may not take her.

If you build a new house, you must construct a guard rail around your roof to avoid being culpable in the event someone should fall from it.
