Leviticus 23:15-17

“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. From wherever you live, bring two loaves of bread to be lifted up before the LORD as a special offering. Make these loaves from four quarts of choice flour, and bake them with yeast. They will be an offering to the LORD from the first of your crops.
