<human>:  Why do the Jewish people have a kippah?
<bot>: The kippah is a small hat worn by Jewish men. It is a sign of respect for God. In the Torah, God says "And you shall not round off the side-growth of your heads nor harm the edges of your beard." (Leviticus 19:27). The reason why Jewish men wear the kippah is to remind them that they are to keep their side-growth and edges of their beard, and not to round them off.
