Leviticus 23:15-22

“You shall count seven full weeks from the day after the Sabbath, from the day that you brought the sheaf of the wave offering. You shall count fifty days to the day after the seventh Sabbath. Then you shall present a grain offering of new grain to the LORD. You shall bring from your dwelling places two loaves of bread to be waved, made of two tenths of an ephah. They shall be of fine flour, and they shall be baked with leaven, as firstfruits to the LORD. And you shall present with the bread seven lambs a year old without blemish, and one bull from the herd and two rams. They shall be a burnt offering to the LORD, with their grain offering and their drink offerings, a food offering with a pleasing aroma to the LORD. And you shall offer one male goat for a sin offering, and two male lambs a year old as a sacrifice of peace offerings. And the priest shall wave them with the bread of the firstfruits as a wave offering before the LORD, with the two lambs. They shall be holy to the LORD for the priest. And you shall make a proclamation on the same day. You shall hold a holy convocation. You shall not do any ordinary work. It is a statute forever in all your dwelling places throughout your generations. “And when you reap the harvest of your land, you shall not reap your field right up to its edge, nor shall you gather the gleanings after your harvest. You shall leave them for the poor and for the sojourner: I am the LORD your God.”
