Philo Judaeus De Virtutibus 90

And who is there who can avoid admiring the proclamation or commandment about reapers and gatherers of the fruit of the vineyard? ¹ For Moses commands that at the time of harvest the farmer shall not gather up the corn which falls from the sheaves, and that he shall not cut down all the crop, but that he shall leave a portion of the field unreaped, by this law rendering the rich magnanimous and communicative of their wealth, from being compelled thus to neglect some portion of their own lawful property, and not to be eager to save it all, nor to collect it all together, not to bring it all home and lay it up in store, and making the poor at the same time more cheerful and contented. For as the poor have no property of their own, he allows them to go into the fields of their fellow countrymen, and to reap of what they have left as if it were their own.
