'Thirty Pieces of Silver' in the Bible

Then said I unto them, If it be good in your eyes, give me my wage, and, if not, forbear. So they weighed out my wage, thirty pieces of silver.

Then said Yahweh unto me, Cast it into the treasury, the magnificent price at which I had been valued by them! So I took the thirty pieces of silver, and cast them, in the house of Yahweh, into the treasury.
