Translation
When you beat your olive trees, do not go over the boughs again; it shall be for the foreigners, the fatherless and the widows.
Paraphrase
When you are shaking the branches of your olive trees to remove the olives (which are your primary source of the oil used in cooking and several other things), do not recheck the boughs a second time; what remains on the tree must be left there for
those who have trouble finding work, and those who have no close relatives to care for them.
