Traditionally in the Christian Church, this day is known as Maundy Thursday. The term Maundy comes from the Latin word mandatum (from which we get our English word mandate), from a verb that means "to give," "to entrust," or "to order." The term is usually translated "commandment," from John's account of this Thursday night.

John 13:1-17 New Living Translation (NLT)
13:1 Before the Passover celebration, Jesus knew that his hour had come to leave this world and return to his Father. He had loved his disciples during his ministry on earth, and now he loved them to the very end. 2 It was time for supper, and the devil had already prompted Judas, son of Simon Iscariot, to betray Jesus. 3 Jesus knew that the Father had given him authority over everything and that he had come from God and would return to God. 4 So he got up from the table, took off his robe, wrapped a towel around his waist, 5 and poured water into a basin. Then he began to wash the disciples’ feet, drying them with the towel he had around him.
6 When Jesus came to Simon Peter, Peter said to him, “Lord, are you going to wash my feet?”
7 Jesus replied, “You don’t understand now what I am doing, but someday you will.”
8 “No,” Peter protested, “you will never ever wash my feet!”
Jesus replied, “Unless I wash you, you won’t belong to me.”
9 Simon Peter exclaimed, “Then wash my hands and head as well, Lord, not just my feet!”
10 Jesus replied, “A person who has bathed all over does not need to wash, except for the feet, to be entirely clean. And you disciples are clean, but not all of you.” 11 For Jesus knew who would betray him. That is what he meant when he said, “Not all of you are clean.”

Hymn:
Then take the towel, and break the bread,
and humble us, and call us friends.
Suffer and serve till all are fed
and show how grandly love intends
to work till all creation sings,
to fill all worlds, to crown all things.

12 After washing their feet, he put on his robe again and sat down and asked, “Do you understand what I was doing? 13 You call me ‘Teacher’ and ‘Lord,’ and you are right, because that’s what I am. 14 And since I, your Lord and Teacher, have washed your feet, you ought to wash each other’s feet. 15 I have given you an example to follow. Do as I have done to you. 16 I tell you the truth, slaves are not greater than their master. Nor is the messenger more important than the one who sends the message. 17 Now that you know these things, God will bless you for doing them.

Poem:
Blessed Jesus, at your word
we are gathered all to hear you;
let our hearts and souls be stirred
now to seek and love and fear you;
by your teachings true and holy;
drawn from earth to love you solely.

Mark 14:22-25 New Living Translation (NLT)
14:22 As they were eating, Jesus took some bread and blessed it. Then he broke it in pieces and gave it to the disciples, saying, "Take it, for this is my body." 23 And he took a cup of wine and gave thanks to God for it. He gave it to them, and they all drank from it. 24 And he said to them, "This is my blood, which confirms the covenant between God and his people. It is poured out as a sacrifice for many. 25 I tell you the truth, I will not drink wine again until the day I drink it new in the Kingdom of God."

Hymn:
O what an act of majesty!
O what a love beyond degree!
O what a hallowed hour of blessing!
Here soul and body are supplied,
and we show forth that Jesus died,
when in this feast our Lord confessing.

John 13:33-35 New Living Translation (NLT)
33 Dear children, I will be with you only a little longer. And as I told the Jewish leaders, you will search for me, but you can’t come where I am going. 34 So now I am giving you a new commandment: Love each other. Just as I have loved you, you should love each other. 35 Your love for one another will prove to the world that you are my disciples.”

John 14:15-21 New Living Translation (NLT)
15 “If you love me, obey my commandments. 16 And I will ask the Father, and he will give you another Advocate, who will never leave you. 17 He is the Holy Spirit, who leads into all truth. The world cannot receive him, because it isn’t looking for him and doesn’t recognize him. But you know him, because he lives with you now and later will be in you. 18 No, I will not abandon you as orphans—I will come to you. 19 Soon the world will no longer see me, but you will see me. Since I live, you also will live. 20 When I am raised to life again, you will know that I am in my Father, and you are in me, and I am in you. 21 Those who accept my commandments and obey them are the ones who love me. And because they love me, my Father will love them. And I will love them and reveal myself to each of them.”
