Exodus 34:22

And thou shalt keep to me the feast of weeks, the beginning of wheat-harvest; and the feast of ingathering in the middle of the year.

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

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