And he said, "There was a man who had two sons; and the younger of them said to his father, 'Father, give me the share of property that falls to me.' And he divided his living between them. Not many days later, the younger son gathered all he had and took his journey into a far country, and there he squandered his property in loose living. And when he had spent everything, a great famine arose in that country, and he began to be in want. So he went and joined himself to one of the citizens of that country, who sent him into his fields to feed swine. And he would gladly have fed on the pods that the swine ate; and no one gave him anything.
Matthew 7:6
"Do not give dogs what is holy; and do not throw your pearls before swine, lest they trample them under foot and turn to attack you."
Mark 5:9-13
And Jesus asked him, "What is your name?" He replied, "My name is Legion; for we are many." And he begged him eagerly not to send them out of the country. Now a great herd of swine was feeding there on the hillside; and they begged him, "Send us to the swine, let us enter them." So he gave them leave. And the unclean spirits came out, and entered the swine; and the herd, numbering about two thousand, rushed down the steep bank into the sea, and were drowned in the sea.
Matthew 15:22-28
And behold, a Canaanite woman from that region came out and cried, "Have mercy on me, O Lord, Son of David; my daughter is severely possessed by a demon." But he did not answer her a word. And his disciples came and begged him, saying, "Send her away, for she is crying after us." He answered, "I was sent only to the lost sheep of the house of Israel." But she came and knelt before him, saying, "Lord, help me." And he answered, "It is not fair to take the children's bread and throw it to the dogs." She said, "Yes, Lord, yet even the dogs eat the crumbs that fall from their masters' table." Then Jesus answered her, "O woman, great is your faith! Be it done for you as you desire." And her daughter was healed instantly.
Luke 16:19-21
"There was a rich man, who was clothed in purple and fine linen and who feasted sumptuously every day. And at his gate lay a poor man named Lazarus, full of sores, who desired to be fed with what fell from the rich man's table; moreover the dogs came and licked his sores."
