“From the day after the Sabbath, from the day on which you bring the sheaf of the elevation offering, you shall count off seven weeks. They shall be complete. You shall count until the day after the seventh Sabbath, fifty days. Then you shall present an offering of new grain to Yahweh. You shall bring from your settlements two loaves of bread as an elevation offering, each made of two-tenths of an ephah. They shall be of choice flour, baked with leaven, as first fruits to Yahweh. You shall present with the bread seven lambs a year old without blemish, one young bull, and two rams. They shall be a burnt offering to Yahweh, along with their grain offering and their drink offerings, an offering by fire as a pleasing odor to Yahweh. You shall also offer one male goat for a sin offering, and two male lambs a year old as a sacrifice of well-being. The priest shall raise them with the bread of the first fruits as an elevation offering before Yahweh, together with the two lambs. They shall be holy to Yahweh for the priest. On that same day you shall make a proclamation. You shall hold a holy convocation. You shall not work at your occupations. It is a statute forever in all your settlements throughout your generations. When you reap the harvest of your land, you shall not reap your field to its very edges of your field, or gather the gleanings of your harvest. You shall leave them for the poor and for the aliens. I am Yahweh your God.”
Once again, we are in the area of a settled farming community in the Promised Land, not in the wilderness. 7 weeks after the first harvest you will make an offering, probably because of the wheat harvest. This 7 week period is 50 days since you presented the first fruits of the harvest. Thus, it came to be called Pentecost based on the Greek translation of 50 days. However, this harvest leaves the very edges of the field and the gleanings for the poor. There was an elaborate offering with 2 loaves of leavened bread made with 20% of a bushel of choice flour as the first fruits to Yahweh. This feast has leavened bread and not the unleavened bread. Then you need 7 one year old unblemished lambs, 1 young bull, and 2 rams, quite a large herd of 10 animals. All this makes up the grain offering and the burnt offering so that there is a pleasing odor to Yahweh. However, there is more. You have a sin offering of a male goat and 2 male lambs as a well-being offering. This makes 13 animals. Obviously this is not one individual but a group of people. On the same day that you shall make a proclamation, you hold a holy convocation and you do not work at your occupations.
