'Poor' in the Bible

So the Lord sent Nathan to David. When he came to David, Nathan said, "There were two men in a certain city, one rich and the other poor.

But the poor man had nothing except for a little lamb he had acquired. He raised it, and it grew up alongside him and his children. It used to eat his food, drink from his cup, and sleep in his arms. It was just like a daughter to him.

"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."
