Clement of Alexandria

Do you see how the law proclaims simultaneously the justice and goodness of God, who provides food unstintingly for all? Again, in the grape harvest the harvesters are forbidden to go back and cut anything that has been left over or to collect fallen grapes. The same rules are applied to olive gatherers. In fact the principle of tithing crops and flocks was an education in honoring the divine. We are not to be totally absorbed by profit but to share humanely with the neighbor as well.
