Leviticus 23:20

18You shall present with the bread seven lambs without defect a year old, one young bull, and two rams. They shall be a burnt offering to the LORD, with their meal offering and their drink offerings, even an offering made by fire, of a sweet aroma to the LORD.

19You shall offer one male goat for a sin offering, and two male lambs a year old for a sacrifice of peace offerings.

20The priest shall wave them with the bread of the first fruits for a wave offering before the LORD, with the two lambs. They shall be holy to the LORD for the priest.

21You shall make proclamation on the same day that there shall be a holy convocation to you. You shall do no regular work. This is a statute forever in all your dwellings throughout your generations.

22“‘When you reap the harvest of your land, you must not wholly reap into the corners of your field. You must not gather the gleanings of your harvest. You must leave them for the poor and for the foreigner. I am the LORD your God.’”
