Exodus 34:22

And you are to celebrate the Feast of Weeks with the firstfruits of the wheat harvest, and the Feast of Ingathering at the turn of the year.

Note That is, Shavuot, the late spring feast of pilgrimage to Jerusalem; it is also known as the Feast of Harvest (see Exodus 23:16) or the Feast of Pentecost (see Acts 2:1).

Note That is, Sukkot, the autumn feast of pilgrimage to Jerusalem; it is later called the Feast of Tabernacles (or Booths or Shelters).

And thou shalt observe the feast of weeks, of the firstfruits of wheat harvest, and the feast of ingathering at the year’s end.

Note year’s end: Heb. revolution of the year

“You shall observe the feast of weeks with the first fruits of wheat harvest, and the feast of harvest at the year’s end.

And thou shalt observe the feast of weeks, even of the first-fruits of wheat harvest, and the feast of ingathering at the year’s end.
