Exodus 38:26-27

a beka a head, that is, half a shekel, after the shekel of the sanctuary, for every one that passed over to them that were numbered, from twenty years old and upward, for six hundred thousand and three thousand and five hundred and fifty men. And the hundred talents of silver were for casting the sockets of the sanctuary, and the sockets of the veil; a hundred sockets for the hundred talents, a talent for a socket.
