'Shekels of Silver' in the Bible

I said to them, “If it is good in your sight, give me my wages; but if not, never mind!” So they weighed out thirty shekels of silver as my wages.

Then the Lord said to me, “Throw it to the potter, that magnificent price at which I was valued by them.” So I took the thirty shekels of silver and threw them to the potter in the house of the Lord.
