Leviticus 23:20

16 You shall count off fifty days until the day after the seventh Sabbath, and then present an offering of new grain to the LORD.

17 Bring two loaves of bread from your dwellings as a wave offering, each made from two-tenths of an ephah of fine flour, baked with leaven, as the firstfruits to the LORD.

18 Along with the bread you are to present seven unblemished male lambs a year old, one young bull, and two rams. They will be a burnt offering to the LORD, together with their grain offerings and drink offerings—an offering made by fire, a pleasing aroma to the LORD.

19 You shall also prepare one male goat as a sin offering and two male lambs a year old as a peace offering.

20 The priest is to wave the lambs as a wave offering before the LORD, together with the bread of the firstfruits. The bread and the two lambs shall be holy to the LORD for the priest.

21 On that same day you are to proclaim a sacred assembly, and you must not do any regular work. This is to be a permanent statute wherever you live for the generations to come.

22 When you reap the harvest of your land, do not reap all the way to the edges of your field or gather the gleanings of your harvest. Leave them for the poor and the foreign resident. I am the LORD your God.’”

23 The LORD also said to Moses,

24 “Speak to the Israelites and say, ‘On the first day of the seventh month you are to have a day of rest, a sacred assembly announced by trumpet blasts.
