'Shekels of Silver' in the Bible

Joab said to the man who informed him, “You saw him! Why then did you not strike him there to the ground? I would have given you ten pieces of silver and a belt.”

And the man said to Joab, Though I should receive a thousand shekels of silver in my hand, yet would I not put forth my hand against the king's son: for in our hearing the king charged thee and Abishai and Ittai, saying, Beware that none touch the young man Absalom.

And the king said unto Araunah, Nay; but I will surely buy it of thee at a price: neither will I offer burnt offerings unto the LORD my God of that which doth cost me nothing. So David bought the threshingfloor and the oxen for fifty shekels of silver.
