Where is the Lamb?

As the disciples gathered with Jesus in the upper room to celebrate the Passover they had the bread, the wine but they didn't have the lamb.  Some may have seen that as on oversight but not to Jesus.  He knew that they had the Lamb.  He was the Lamb.  As He took the bread and broke it He said that this was His body that would be broken for them but when He took the wine He said that it was the new covenant.  Everything was there.  Nothing was overlooked.
