Leviticus 23:9-19

9 The LORD spoke to Moses,
10 "Tell the Israelites: When you come to the land I am going to give you and you harvest grain, bring the priest a bundle of the first grain you harvest.
11 He will present it to the LORD so that you will be accepted. He will present it on the day after Passover.
12 On the day you present the bundle, you must sacrifice a one-year-old male lamb that has no defects as a burnt offering to the LORD.
13 Bring a grain offering of four quarts of flour mixed with olive oil with it. This will be a sacrifice by fire made to the LORD, a soothing aroma. Use one quart of wine for the wine offering.
14 Don't eat bread, roasted grain, or fresh grain until this same day, when you bring the offering to your God. It is a permanent law for generations to come wherever you live
15 "Count seven full weeks from the day after Passover (the day you bring the bundle of grain as an offering presented to the LORD)
16 until the day after the seventh week. This is a total of fifty days. Then bring a new grain offering to the LORD.
17 Bring two loaves of bread from your homes to present to the LORD. Bake them with four quarts of flour. They are the first harvested grain for the LORD.
18 With the bread bring seven one-year-old lambs that have no defects, one bull, and two rams. They will be a burnt offering to the LORD. With these offerings also bring grain and wine offerings. They will be a sacrifice by fire, a soothing aroma to the LORD.
19 Also sacrifice one male goat as an offering for sin and two one-year-old lambs as a fellowship offering
