Leviticus 23:29 "For any person that shall not be afflicted on that same day, shall be cut off from his peoplet"

Yom Kippur is a very holy day. We spend most of the day praying and asking forgiveness from HaShem for all our sins and ask that He grant us a good year.

On Yom Kippur, we are forbidden to eat anything.

Boys under the age of thirteen and girls younger than twelve, may eat because otherwise, they might become weak and unhealthy.
