'Pounds' in the Bible

It’s like yeast that a woman took and mixed into 50 pounds of flour until it spread through the entire mixture.”

And he called his ten servants, and delivered them ten pounds, and said unto them, Occupy till I come.

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

(And they said unto him, Lord, he hath ten pounds.)
