'Pound' in the Bible

And he called ten of his servants and gave each of them a pound, instructing them to trade with the money during his absence.

Then came the first, saying, Lord, thy pound hath gained ten pounds.

And the second came, saying, Lord, thy pound hath gained five pounds.

And another came, saying, Lord, behold, here is thy pound, which I have kept laid up in a napkin:

And he said unto them that stood by, Take from him the pound, and give it to him that hath ten pounds.
