'Harvest' in the Bible

"You shall not delay to offer from your harvest and from the outflow of your presses. "You shall give the firstborn of your sons to me.

And the feast of harvest, the first fruits of your labors, which you sow in the field: and the feast of harvest, at the end of the year, when you gather in your labors out of the field.

"Six days you shall work, but on the seventh day you shall rest: in plowing time and in harvest you shall rest.

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