'Harvest' 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.
"Tell the Israelis that when you enter the land that I'm about to give you and gather its produce, you are to bring a sheaf from the first portion of your harvest to the priest,
Furthermore, when you harvest the produce of your land, you are not to harvest all the way to the corners of your field or gather the gleanings of your harvest. Leave them for the poor and resident alien. I am the LORD your God."
The fiftieth year is to be a year of jubilee for you. You are not to sow or harvest the spilled kernels that grow of themselves or pick grapes from the untrimmed vines
That way, you are to sow in the eighth year, eating the produce from the old harvest. Until the ninth year when its produce comes in, you'll eat from the old harvest."
"If a person consecrates to the LORD a portion of the field from his inheritance, then your valuation is to be based on its capacity for yielding a harvest. Each omer of barley is to be valued at 50 shekels of silver.
