Leviticus 23:15

12 On the day when you wave the sheaf, you shall offer a male lamb without defect a year old for a burnt offering to the LORD.

13 The meal offering with it shall be two tenths of an ephah of fine flour mixed with oil, an offering made by fire to the LORD for a pleasant aroma; and the drink offering with it shall be of wine, the fourth part of a hin.

14 You must not eat bread, or roasted grain, or fresh grain, until this same day, until you have brought the offering of your God. This is a statute forever throughout your generations in all your dwellings.

15 “‘You shall count from the next day after the Sabbath, from the day that you brought the sheaf of the wave offering: seven Sabbaths shall be completed.

16 The next day after the seventh Sabbath you shall count fifty days; and you shall offer a new meal offering to the LORD.

17 You shall bring out of your habitations two loaves of bread for a wave offering made of two tenths of an ephah of fine flour. They shall be baked with yeast, for first fruits to the LORD.

18 You shall present with the bread seven lambs without defect a year old, one young bull, and two rams. They shall be a burnt offering to the LORD, with their meal offering and their drink offerings, even an offering made by fire, of a sweet aroma to the LORD.
