Leviticus 23:15-22

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. You shall count fifty days to the day after the seventh sabbath; then you shall present a new grain offering to Yahweh. You 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 Yahweh. Along 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 Yahweh, with their grain offering and their drink offerings, an offering by fire of a soothing aroma to Yahweh. You shall also offer one male goat for a sin offering and two male lambs one year old for a sacrifice of peace offerings. The priest shall then wave them with the bread of the first fruits for a wave offering with two lambs before Yahweh; they are to be holy to Yahweh for the priest. "On 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. 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 Yahweh your Elohim."'
