TSK · Leviticus 23:31

This is to be a perpetual statute for you to make atonement for the Israelites for all their sins once a year.” So he did just as the LORD had commanded Moses.

“‘On this very day you must proclaim an assembly; it is to be a holy assembly for you. You must not do any regular work. This is a perpetual statute in all the places where you live throughout your generations.
