In the New Testament, Jesus is referred to as the King of the Judeans, both at the beginning of his life and at the end. In the Koine Greek of the New Testament, e.g. in John 19:3, this is written Basileus ton Ioudaion (βασιλεὺς τῶν Ἰουδαίων).
Both uses of the title lead to dramatic results in the New Testament accounts. In the account of the Nativity of Jesus in the Gospel of Matthew, the wise men (i.e. Magi) who come from the east call Jesus the "King of the Judeans", causing King Herod to order the Massacre of the Innocents. Towards the end of the accounts of all four Canonical Gospels, in the narrative of the Passion of Jesus, the use of the "King of the Judeans" title leads to charges against Jesus that result in his Crucifixion.
The initialism INRI (Latin: Iēsūs/Iēsus Nazarēnus, Rēx Iūdaeōrum) represents the Latin inscription which in English reads as "Jesus the Nazarene, King of the Jews" and John 19:20 states that this was written in three languages — Aramaic, Latin, and Greek — during the crucifixion of Jesus. The Greek version of the initialism read ΙΝΒΙ, representing Ἰησοῦς ὁ Ναζωραῖος ὁ Bασιλεὺς τῶν Ἰουδαίων  which is best translated, "Jesus the Nazorean, King of the Judeans."
In the New Testament, the "King of the Jews” title is used only by the gentiles, namely by the Magi, Pontius Pilate, and the Roman soldiers. In contrast, the Jewish leaders use the designation "King of Israel". The phrase has also been translated King of the Judeans (see Ioudaioi).
In the account of the Nativity of Jesus in the Gospel of Matthew the Biblical Magi go to see King Herod the Great in Jerusalem and in Matthew 2:2 ask him: "Where is He that is born King of the Judeans?"
The question troubles Herod who considers the title his own, and in Matthew 2:7-8 he attempts to trick the Magi to reveal the exact location of the newborn King of the Jews. However, once the Magi depart without informing Herod of the location of Jesus, Herod orders the execution of all young male children in the village of Bethlehem, in the episode known as the Massacre of the Innocents (Matthew 2:16) to avoid the loss of his throne to the newborn King of the Jews whose birth had been announced to him by the Magi.
In the accounts of the Passion of Jesus, the title King of the Judeans is used on three separate occasions. In the first such episode, all four Gospels state that the title was used for Jesus when he was interviewed by Pilate and that his Crucifixion was based on that charge, as in Matthew 27:11, Mark 15:2, Luke 23:3 and John 18:33.
The use of the terms King and Kingdom, and the role of the Jews in using the term King to accuse Jesus are central in the discussion between Jesus and Pilate. In John 18:34 Jesus hints that the King accusation did not originate with Pilate but with "others" and in John 18:36 he states: "My kingdom is not of this world". However Jesus does not directly deny being the King of the Jews.
In the New Testament, Pilate writes "Jesus the Nazarene, King of the Judeans" as a sign to be affixed to the cross of Jesus. John 19:21 states that the Jews told Pilate: "Do not write King of the Jews" but instead write that Jesus had merely claimed that title, but Pilate wrote it anyway. Pilate's response to the protest is recorded by John: "What I have written, I have written."
After the trial by Pilate and after the Flagellation of Christ episode, the soldiers mock Jesus as the King of Jews by putting a purple robe (that signifies royal status) on him, place a Crown of Thorns on his head, and beat and mistreat him in Matthew 27:29-30, Mark 15:17-19 and John 19:2-3.
The continued reliance on the use of the term King by the Judeans to press charges against Jesus is a key element of the final decision to crucify him. In John 19:12 Pilate seeks to release Jesus, but the Jews object, saying: "If thou release this man, thou art not Caesar's friend: every one that maketh himself a king speaketh against Caesar" bringing the power of Caesar to the forefront of the discussion. In John 19:12 the Jews then cry out: "Crucify him! ... We have no king but Caesar."
The use of the term "King of the Judeans" by the early Church after the death of Jesus was thus not without risk, for this term could have opened them to prosecution as followers of Jesus, who was accused of possible rebellion against Rome.
The final use of the title only appears in Luke 23:36-37. Here, after Jesus has carried the cross to Calvary and has been nailed to the cross, the soldiers look up on him on the cross, mock him, offer him vinegar and say: "If thou art the King of the Jews, save thyself." In the parallel account in Matthew 27:42 the Jewish priests mock Jesus as "King of Israel", saying: "He is the King of Israel; let him now come down from the cross, and we will believe on him."
In the New Testament, the "King of the Jews” title is used only by the gentiles, namely by the Magi, Pontius Pilate, Roman soldiers. In contrast the Jewish leaders prefer the designation "King of Israel", as in Matthew 27:42, Mark 15:32. But from Pilate's perspective, it is the term "King" (regardless of Jews or Israel) which is sensitive, for it implies possible rebellion against the Roman Empire.
The acronym INRI represents the Latin inscription IESVS·NAZARENVS·REX·IVDÆORVM (Iesus Nazarenus, Rex Iudaeorum), in English reads as "Jesus the Nazarene, King of the Jews". John 19:20 states that this was written in three languages: Hebrew, Latin and Greek and was put on the cross of Jesus. The Greek version reads ΙΝΒΙ.
Devotional enthusiasm greeted the discovery by Cardinal Pedro González de Mendoza in 1492 of what was acclaimed as the actual tablet, said to have been brought to Rome by Saint Helena, mother of Emperor Constantine.
In Western Christianity, most crucifixes and many depictions of the crucifixion of Jesus include a plaque or parchment placed above his head, called a titulus, or title, bearing only the Latin letters INRI, occasionally carved directly into the cross and usually just above the head of Jesus. In the Eastern Church "King of Glory" (τῆς Δόξης, tês Dóxēs) may be used.
In Eastern Christianity, both the Eastern Orthodox Church and the Eastern Catholic particular churches sui iuris use the Greek letters ΙΝΒΙ, based on the Greek version of the inscription Ἰησοῦς ὁ Ναζωραῖος ὁ βασιλεὺς τῶν Ἰουδαίων (Iēsûs ho Nazōraêos ho basileùs tôn Iudaéōn). Some representations change the title to "ΙΝΒΚ," ὁ Bασιλεὺς τοῦ κόσμου (ho Basileùs tû kósmu, "The King of the World"), or to ὁ Bασιλεὺς τῆς Δόξης (ho Basileùs tês Dóxēs, "The King of Glory"), not implying that this was really what was written but reflecting the tradition that icons depict the spiritual reality rather than the physical reality. Some other Eastern Orthodox churches (such as the Romanian Orthodox Church) use the Latin version, INRI, which is the same to the abbreviation of the Romanian equivalent. The Russian Orthodox Church uses ІНЦІ (INCI, the Church Slavonic equivalent of ΙΝΒΙ) or the abbreviation Царь Славы (Carĭ Slavy, "King of Glory").
