Considering the cultural context of ancient Israel, what primary purpose did the law of 'gleaning' (leaving leftover crops for the poor) serve, beyond simply providing food?

A To ensure the wealthy landowners maintained social status within the community. B To create a system of economic equality, redistributing wealth from the rich to the poor. C To reinforce the concept of communal responsibility and demonstrate God's provision for the vulnerable (Leviticus 19:9-10). D To provide a means for the poor to pay taxes to the Levitical priests.
