'Poor' in the Bible

Yahweh sent Nathan to David. He came to him, and said to him, "There were two men in one city; the one rich, and the other poor.

but the poor man had nothing, except one little ewe lamb, which he had bought and raised. It grew up together with him, and with his children. It ate of his own food, drank of his own cup, and lay in his bosom, and was to him like a daughter.

A traveler came to the rich man, and he spared to take of his own flock and of his own herd, to dress for the wayfaring man who had come to him, but took the poor man's lamb, and dressed it for the man who had come to him."
