That might seem like a statute that is just tacked onto the end, but when we pull all the themes together, we can see how that verse fits perfectly. The Feast of Harvest represents a harvest of our labors, labors that God’s intends to benefit fellow man, as the grain offering pictures. And within that theme is this further instruction not to be exacting, even in harvesting what is our own, but to allow the poor and the stranger to also labor so they can have something. It shows supporting the well-being of our fellow man.
