Righteous is the man who gives his mother his house, but even more righteous is the man who gives his mother his donkey.

This man is more righteous than the one who gives his mother his house. The reason is because the donkey is a more useful animal than a house. A house cannot move, but a donkey can. A donkey can be used for transportation, carrying goods, or plowing fields. A house cannot do any of these things. Therefore, the man who gives his mother a donkey is more righteous than the one who gives her a house.
