The Agape (Melave Malka)

On the night that Yeshua Sar HaPanim was betrayed by the Sicari's son, Yeshua gave his disciples a Zava'a of love to do in remembrance of him. Birkat Hamazon Havdalah (Ner, Besamim, Birkat HaMazon Havdalah per Hillel cf Berakhot 52b). The story has 3 parts.

1. SHIRAYIM (Matt 26:26, Mark 14:22, Luke 22:15-16, John 13:4-5, 1.Corinth 11:23)

On the night He was betrayed, the Lord Yeshua ate. After Yeshua and his disciples had been enjoying the Feast of the 15th of Nisan, while they were eating, he expressed how happy he was that he had been able to celebrate this last Passover together with them and said that he would not eat it again until it is fulfilled in the kingdom of God. Then Yeshua washed his disciples feet and announced his betrayal and having:
a) eaten bread
b) spoken the Eulogia (Pesukim)
c) and broken it up into shirayim
d) he gave it to his disciples telling them to take it to eat (for Melave Malka) and this is his Tzura.

2. EUCHARISTIC HAVDALAH (Matt 26:27-29, Mark 14:23-25, Luke 22:17-18)

Afterwards:
a) He took the Kos Shel Brakha
b) Recited Havdalah
c) and gave it to His disciples saying Take this and Drink from it, all of you. And He said to them: This is My effort (blood, sweat & tears) for the covenant which is poured out for many for the forgiveness of sins. Divide it among yourselves for truly I tell you that I will no longer drink of the fruit of the vine from now on until that day when I drink it anew with you in My Father’s kingdom when the kingdom of God comes.

3. THE POST HAVDALAH HYMN & THE TRAITOR (1.Corinth 11:24-29, Luke 22:19-22, John 13:18-35, Matt 26:30, Mark 14:26)

Luke
And he took a piece of the eucharistic bread (which he had broken and given to them) saying: “This is My Tzura (Soma), given for you; do this in remembrance of Me.” In the same way, after supper He took the cup, saying, “This cup is the Brith Khadasha in My blood, which is poured out for you. Do this, as often as you drink it, in remembrance of Me.” “Look! The hand of My betrayer is with Mine on the table. Indeed, the Son of Man will go as it has been determined, but woe to that man who betrays Him.” 

Paul
For as often as you eat this bread and drink this cup, you proclaim the Lord’s death until He comes. Therefore, whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of sinning against the Tzura and blood of the Lord. Each one must examine himself before he eats of the bread and drinks of the cup. For anyone who eats and drinks without recognizing the Tzura eats and drinks judgment on himself.

John
Lazarus, was reclining at Yeshua's side. So Simon Peter motioned to Lazarus to ask Yeshua concerning the traitor. Leaning back against Yeshua, Lazarus asked, “Lord, who is it?” Yeshua answered, “It is the one to whom I give this morsel after I have dipped it.” Then He dipped the morsel and gave it to Judas son of Simon Iscariot. And when Judas had taken the morsel, Satan entered into him. Then Yeshua said to Judas, “What you are about to do, do quickly.” But no one at the table knew why Yeshua had said this to him. Since Judas kept the money bag, some thought that Yeshua was telling him to buy what was needed for the feast, or to give something to the poor. As soon as he had received the morsel, Judas went out into the night. When Judas had gone out, Yeshua said, “Now the Son of Man is glorified, and God is glorified in Him. If God is glorified in Him, God will also glorify the Son in Himself—and will glorify Him immediately. Little children, I am with you only a little while longer. You will look for Me, and as I said to the Judaeans, so now I say to you: ‘Where I am going, you cannot come.’ A new commandment I give you: Love one another. As I have loved you, so you also must love one another. By this everyone will know that you are My disciples, if you love one another.”

Matt&Mark
And when they had sung this hymn, they went out to the Mount of Olives.
