<P> In the Gospel of John, after the departure of Judas from the Last Supper, Jesus tells his remaining disciples that he will be with them for only a short time, then gives them a New Commandment, stating: "A new command I give you: Love one another . As I have loved you, so you must love one another . By this everyone will know that you are my disciples, if you love one another ." in John 13: 34--35 . Two similar statements also appear later in John 15: 12: "My command is this: Love each other as I have loved you", and John 15: 17: "This is my command: Love each other ." </P> <P> At the Last Supper in the Gospel of John, Jesus gives an extended sermon to his disciples . This discourse resembles farewell speeches called testaments, in which a father or religious leader, often on the deathbed, leaves instructions for his children or followers . </P> <P> This sermon is referred to as the Farewell discourse of Jesus, and has historically been considered a source of Christian doctrine, particularly on the subject of Christology . John 17: 1--26 is generally known as the Farewell Prayer or the High Priestly Prayer, given that it is an intercession for the coming Church . The prayer begins with Jesus's petition for his glorification by the Father, given that completion of his work and continues to an intercession for the success of the works of his disciples and the community of his followers . </P> <P> Historians estimate that the date of the crucifixion fell in the range AD 30--36 . Physicists such as Isaac Newton and Colin Humphreys have ruled out the years 31, 32, 35, and 36 on astronomical grounds, leaving 7 April AD 30 and 3 April AD 33 as possible crucifixion dates . Humphreys proposes narrowing down the date of the Last Supper as having occurred in the evening of Wednesday, 1 April AD 33, by revising Annie Jaubert's double - Passover theory . The rationale is as follows . </P>
