Rights of Harvest and Gleaning

Deuteronomy 23:24-25

`When thou comest in unto the vineyard of thy neighbour, then thou hast eaten grapes, according to thy desire, thy sufficiency; but into thy vessel thou dost not put any .

When thou comest in among the standing-corn of thy neighbour, then thou hast plucked the ears with thy hand, but a sickle thou dost not wave over the standing-corn of thy neighbour.
