⁷ And thou shalt ^[a]roast and eat it in the place which Jehovah thy God shall choose: and thou shalt turn in the morning, and go unto thy tents. ⁸ Six days thou shalt eat unleavened bread; and on the seventh day shall be a solemn assembly to Jehovah thy God; thou shalt do no work therein.

⁹ Seven weeks shalt thou number unto thee: from the time thou beginnest to put the sickle to the standing grain shalt thou begin to number seven weeks.
