Leviticus 23:15-22

¹⁵‘You shall also count for yourselves from the day after the sabbath, from the day when you brought in the sheaf of the wave offering; there shall be seven complete sabbaths. ¹⁶You shall count fifty days to the day after the seventh sabbath; then you shall present a new grain offering to the Lord. ¹⁷You shall bring in from your dwelling places two loaves of bread for a wave offering, made of two-tenths of an ephah; they shall be of a fine flour, baked with leaven as first fruits to the Lord. ¹⁸Along with the bread you shall present seven one year old male lambs without defect, and a bull of the herd and two rams; they are to be a burnt offering to the Lord, with their grain offering and their drink offerings, an offering by fire of a soothing aroma to the Lord. ¹⁹You shall also offer one male goat for a sin offering and two male lambs one year old for a sacrifice of peace offerings. ²⁰The priest shall then wave them with the bread of the first fruits for a wave offering with two lambs before the Lord; they are to be holy to the Lord for the priest. ²¹On this same day you shall make a proclamation as well; you are to have a holy convocation. You shall do no laborious work. It is to be a perpetual statute in all your dwelling places throughout your generations.

²²‘When you reap the harvest of your land, moreover, you shall not reap to the very corners of your field nor gather the gleaning of your harvest; you are to leave them for the needy and the alien. I am the Lord your God.’”
