Leviticus 23:14-18

Until this very day, until you have brought in the offering of your God, you shall eat neither bread nor roasted grain nor new produce. It is to be a permanent statute throughout your generations in all your dwelling places.

‘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 the Lord.

You shall bring in from your dwelling places two loaves of bread as 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.

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 the Lord, with their grain offering and their drink offerings, an offering by fire of a soothing aroma to the Lord.
