'Poor' in the Bible

Only they would that we should remember the poor; the same which I also was forward to do.

O you foolish and thoughtless and superficial Galatians, who has bewitched you [that you would act like this], to whom—right before your very eyes—Jesus Christ was publicly portrayed as crucified [in the gospel message]?

and now, having known God -- and rather being known by God -- how turn ye again unto the weak and poor elements to which anew ye desire to be in servitude?

And you did not have a poor opinion of me because of the trouble in my flesh, or put shame on it; but you took me to your hearts as an angel of God, even as Christ Jesus.
