Deuteronomy 24:20
When thou beatest thine olive tree, thou shalt not go over the boughs again: it shall be for the stranger, for the fatherless, and for the widow.
When thou beatest thine olive tree,.... With sticks and staves, to get off the olives when ripe:
thou shall not go over the boughs again; to beat off some few that may remain; they were not nicely to examine the boughs over again, whether there were any left or not:
it shall be for the stranger, for the fatherless, and for the widow; who might come into their oliveyards after the trees had been beaten, and gather what were left.
