Leviticus 23:13-17

Its grain offering shall then be two-tenths of an ephah of fine flour mixed with oil, an offering by fire to the Lord for a soothing aroma, with its drink offering, a fourth of a hin of wine.

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.
