'Harvest' in the Bible

{As long as the earth endures}, seed and harvest, cold and heat, summer and winter, day and night will not cease.

And in the days of the wheat harvest, Reuben went and found mandrakes in the field and he brought them to Leah his mother. And Rachel said to Leah, "Please give me some of your son's mandrakes."

For these two years the famine [has been] in the midst of the land, but [there will be] five more years where there is no plowing or harvest.

And it shall happen [that] at the harvest, you must give a fifth to Pharaoh and four-fifths shall be yours, as seed for the field and for your food and for those who [are] in your households, and as food for your little ones."
