Leviticus 23:4-14

⁴ These are the fixed feasts of the Lord, the holy days of worship which you will keep at their regular times. ⁵ In the first month, on the fourteenth day of the month at nightfall, is the Lord's Passover; ⁶ And on the fifteenth day of the same month is the feast of unleavened bread; for seven days let your food be unleavened bread. ⁷ On the first day you will have a holy meeting; you may do no sort of field-work. ⁸ And every day for seven days you will give a burned offering to the Lord; and on the seventh day there will be a holy meeting; you may do no field-work. ⁹ And the Lord said to Moses, ¹⁰ Say to the children of Israel, When you have come to the land which I will give you, and have got in the grain from its fields, take some of the first-fruits of the grain to the priest; ¹¹ And let the grain be waved before the Lord, so that you may be pleasing to him; on the day after the Sabbath let it be waved by the priest. ¹² And on the day of the waving of the grain, you are to give a male lamb of the first year, without any mark, for a burned offering to the Lord. ¹³ And let the meal offering with it be two tenth parts of an ephah of the best meal mixed with oil, an offering made by fire to the Lord for a sweet smell; and the drink offering with it is to be of wine, the fourth part of a hin. ¹⁴ And you may take no bread or dry grain or new grain for food till the very day on which you have given the offering for your God: this is a rule for ever through all your generations wherever you are living.
