"When I decide to stand up for foreign aid, it’s not just about strengthening alliances or promoting democratic values, it’s also about the Biblical call to care for the least of these, for the poor for those at the margins of our society."
I think that must be from Leviticus (23:22):
When you reap the harvest of your land, do not reap to the very edges of your field or gather the gleanings of your harvest.Confiscate the harvests of others. Leave them for the poor and the alien. I am the LORD your God.
