Leviticus 23:9-14 New International Version Anglicized (NIVUK)

9. The Lord said to Moses,

10. ‘Speak to the Israelites and say to them: “When you enter the land I am going to give you and you reap its harvest, bring to the priest a sheaf of the first grain you harvest.

11. He is to wave the sheaf before the Lord so it will be accepted on your behalf; the priest is to wave it on the day after the Sabbath.

12. On the day you wave the sheaf, you must sacrifice as a burnt offering to the Lord a lamb a year old without defect,

13. together with its grain offering of one fifth of an ephah of the finest flour mixed with olive oil – a food offering presented to the Lord, a pleasing aroma – and its drink offering of a quarter of a hin of wine.

14. You must not eat any bread, or roasted or new grain, until the very day you bring this offering to your God. This is to be a lasting ordinance for the generations to come, wherever you live.The Festival of Weeks
