'Price' in the Bible

And kept back part of the price, his wife also being privy to it, and brought a certain part, and laid it at the apostles' feet.

But Peter said, Ananias, why hath Satan filled thine heart to lie to the Holy Ghost, and to keep back part of the price of the land?

Many of them also which used curious arts brought their books together, and burned them before all men: and they counted the price of them, and found it fifty thousand pieces of silver.
