If something is mentioned ONCE in Scripture; you can just toss it out?
17 And on the first day of the Azymes, the disciples came to Jesus, saying: Where wilt thou that we prepare for thee to eat the pasch?
18 But Jesus said: Go ye into the city to a certain man, and say to him: the master saith, My time is near at hand, with thee I make the pasch with my disciples.
19 And the disciples did as Jesus appointed to them, and they prepared the pasch.
20 But when it was evening, he sat down with his twelve disciples.
21 And whilst they were eating, he said: Amen I say to you, that one of you is about to betray me.
22 And they being very much troubled, began every one to say: Is it I, Lord?
23 But he answering, said: He that dippeth his hand with me in the dish, he shall betray me.
24 The Son of man indeed goeth, as it is written of him: but woe to that man by whom the Son of man shall be betrayed: it were better for him, if that man had not been born.
25 And Judas that betrayed him, answering, said: Is it I, Rabbi? He saith to him: Thou hast said it.
26 And whilst they were at supper, Jesus took bread, and blessed, and broke: and gave to his disciples, and said: Take ye, and eat. This is my body.
27 And taking the chalice, he gave thanks, and gave to them, saying: Drink ye all of this.
28 For this is my blood of the new testament, which shall be shed for many unto remission of sins.
29 And I say to you, I will not drink from henceforth of this fruit of the vine, until that day when I shall drink it with you new in the kingdom of my Father.
30 And a hymn being said, they went out unto mount Olivet.
