'Surplus' in the Bible

When they measured it by quarts, the person who gathered a lot had no surplus, and the person who gathered a little had no shortage. Each gathered as much as he needed to eat.

With Your hand, Lord, save me from men,from men of the worldwhose portion is in this life:You fill their bellies with what You have in store;their sons are satisfied,and they leave their surplus to their children.

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.”

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.
