'Harvesting' in the Bible

"When you reap the harvest of your land, you are not to completely finish harvesting the corners of the field that is, you are not to pick what remains after you have reaped your harvest.

Threshing season will extend for you until the season for harvesting grapes, and the season for harvesting grapes will extend until sowing season, so you will eat your bread until you are satisfied, and you will live securely in your land.
