Iain Provan explains the logic of Old Testament commands to accommodate the poor.
Certainly, in the Old Testament, that really counts as a very serious imperative – that you must allow the poor access, that the poor are stakeholders. And so even if you own land, you are supposed to allow some access to the poor to that land. Because in the end of the day, you don’t have absolute ownership of that land. You are only looking after it on behalf of God. You’re a tenant of God. So again, the theological perspective directly impacts the moral duty that you perceive.
