'Sheep' in the Bible

"When a traveler arrived at the rich man's home, he did not want to use one of his own sheep or cattle to feed the traveler who had come to visit him. Instead, he took the poor man's lamb and cooked it for the man who had come to visit him."

When he saw the angel who was destroying the people, David said to the Lord, "Look, it is I who have sinned and done this evil thing! As for these sheep -- what have they done? Attack me and my family."
