From Luke 22:14
So when the hour came, he reclined at the table along with the apostles.+ 15 And he said to them: “I have greatly desired to eat this Passover with you before I suffer; 16 for I tell you, I will not eat it again until it is fulfilled in the Kingdom of God.” 17 And accepting a cup, he gave thanks and said: “Take this and pass it from one to the other among yourselves, 18 for I tell you, from now on, I will not drink again from the product of the vine until the Kingdom of God comes.”+
19 Also, he took a loaf,+ gave thanks, broke it, and gave it to them, saying: “This means my body,+ which is to be given in your behalf.+ Keep doing this in remembrance of me.”+ 20 Also, he did the same with the cup after they had the evening meal, saying: “This cup means the new covenant+ by virtue of my blood,+ which is to be poured out in your behalf.+
21 “But look! the hand of my betrayer is with me at the table.+ 22 For, indeed, the Son of man is going his way according to what has been determined;+ all the same, woe to that man through whom he is betrayed!”+ 23 So they began to discuss among themselves which one of them could really be about to do this.+ ////There was a scripture used ( didn't look it up ) where Jesus told Judas to go and do what he had to do. JWs use it to show Judas wasn't there partaking of the bread and wine at the Lord's evening meal? That however isn't how I read this account in Luke...
