'Surplus' in the Bible

For they all gave out of their surplus, but she out of her poverty has put in everything she possessed—all she had to live on.”

For all these people have put in gifts out of their surplus, but she out of her poverty has put in all she had to live on.”

After the Sabbath ends, each of you should set aside and save something from your surplus in proportion to what you have, so that no collections will have to be made when I arrive.

at the present time your surplus is available for their need, so their abundance may also become available for our need, so there may be equality.
