“And from the day after the Sabbath, from the day on which you bring the sheaf of the elevation offering, you shall count seven full weeks.
You shall observe the Festival of Weeks, the first fruits of wheat harvest, and the Festival of Ingathering at the turn of the year.
“You shall count off seven weeks of years, seven times seven years, so that the period of seven weeks of years gives forty-nine years.
“On the day of the first fruits, when you offer a grain offering of new grain to the Lord at your Festival of Weeks, you shall have a holy convocation; you shall not work at your occupations.
When the day of Pentecost had come, they were all together in one place.
