Or  shall fast; also verse 32
and present a food offering to the Lord.
28And you shall not do any work on that very day, for it is a Day of Atonement, to make atonement for you before the Lord your God. 29For whoever is not afflicted on that very day gshall be cut off from his people. 30And whoever does any work on that very day, that person I will destroy from among his people. 31You shall not do any work. It is a statute forever throughout your generations in all your dwelling places. 32It shall be to you a Sabbath of solemn rest, and you shall afflict yourselves. On the ninth day of the month beginning at evening, from evening to evening shall you keep your Sabbath.”
