'Poor' in the Bible

and oppress not the widow, nor the fatherless, the sojourner, nor the poor; and let none of you devise evil against his brother in your heart.

So I fed the flock of slaughter, verily the poor of the flock. And I took unto me two staves; the one I called Beauty, and the other I called Bands; and I fed the flock.

And it was broken in that day; and thus the poor of the flock that gave heed unto me knew that it was the word of Jehovah.
