And not many days after the younger son gathered all together, and took his journey into a far country, and there wasted his substance with riotous living. And when he had spent all, there arose a mighty famine in that land; and he began to be in want. And he went and joined himself to a citizen of that country; and he sent him into his fields to feed swine. And he would FAIN have filled his belly with the husks that the swine did eat: and no man gave unto him. ( Luke 15:13-16 )
