Leviticus 19:11 - Ellicott's Commentary On The Whole Bible

Ye shall not steal. — This injunction, which forms the eighth commandment of the Decalogue (Exodus 20:15), most probably has here a primary reference to the conduct of the owners of fields and vineyards. They are cautioned that by depriving the poor of his prescribed right to the corner of the fields, and to the gleanings of the harvest and vintage, they commit theft. Hence the Jewish canonists laid it down that he who puts a basket under a vine at the time of gathering grapes robs the poor.
