Leviticus 23:10-16

“Give the following instructions to the people of Israel. When you enter the land I am giving you and you harvest its first crops, bring the priest a bundle of grain from the first cutting of your grain harvest. On the day after the Sabbath, the priest will lift it up before the LORD so it may be accepted on your behalf. On that same day you must sacrifice a one-year-old male lamb with no defects as a burnt offering to the LORD. With it you must present a grain offering consisting of four quarts of choice flour moistened with olive oil. It will be a special gift, a pleasing aroma to the LORD. You must also offer one quart of wine as a liquid offering. Do not eat any bread or roasted grain or fresh kernels on that day until you bring this offering to your God. This is a permanent law for you, and it must be observed from generation to generation wherever you live. “From the day after the Sabbath—the day you bring the bundle of grain to be lifted up as a special offering—count off seven full weeks. Keep counting until the day after the seventh Sabbath, fifty days later. Then present an offering of new grain to the LORD.
