Because the New Testament was originally written in Greek, not Hebrew or Aramaic. Greeks did not use the sound sh, so the evangelists substituted an S sound. Then, to make it a masculine name, they added another S sound at the end. The earliest written version of the name Jesus is Romanized today as Iesous.
Jesus' name in Hebrew was “Yeshua” which translates to English as Joshua.
Jesus, which is the name used by most English-speaking people today, is an English transliteration of a Germanic adaptation, of a Latin transliteration, of a Greek transliteration of an originally Hebrew name, that is simply Yeshua.
Jehovah. Much later in Israel's history (around the 3rd or 2nd century B.C.E.), people stopped pronouncing Yahweh's name aloud, likely as a form of reverence. When they came across the letters for “Yahweh” in the Bible, they would not say “Yahweh,” but replaced it with the Hebrew word for “Lord,” pronounced adonai.
The answer that the biblical story gives is Jesus, Immanuel, God With Us. The reference to this name comes from the prophet Isaiah who first foretold of a virgin or young women conceiving and bearing a child. As the prophet says, this child will be named “Immanuel” (Isa. 7:14).
The most likely suggestion is that it comes from a monogram made of the first three letters of the Greek name for Jesus. In Greek, “Jesus” is ΙΗΣΟΥΣ in uppercase letters and Ἰησοῦς in lower. The first three letters (iota, eta, and sigma) form a monogram, or graphic symbol, written as either IHS or IHC in Latin letters.
Luke 23:45b-46: And the curtain of the temple was torn in two. Then Jesus, calling out with a loud voice, said, "Father, into your hands I commit my spirit!" And having said this he breathed his last.
All modern denominations of Judaism teach that the four letter name of God, YHWH, is forbidden to be uttered except by the High Priest, in the Temple. Since the Temple in Jerusalem no longer exists, this name is never said in religious rituals by Jews. Orthodox and Conservative Jews never pronounce it for any reason.
After the Babylonian Exile (6th century bce), and especially from the 3rd century bce on, Jews ceased to use the name Yahweh for two reasons.
The essential uses of the name of God the Father in the New Testament are Theos (θεός the Greek term for God), Kyrios (i.e. Lord in Greek) and Patēr (πατήρ i.e. Father in Greek). The Aramaic word "Abba" (אבא), meaning "Father" is used by Jesus in Mark 14:36 and also appears in Romans 8:15 and Galatians 4:6.
In English, the name Yeshua is extensively used by followers of Messianic Judaism, whereas East Syriac Christian denominations use the name ʿIsho in order to preserve the Syriac name of Jesus.
"Yahweh" is the Hebrew word for the self-revealed name of the God of the Old Testament. It comes from the Hebrew verb "To be." At its core, "Yahweh" means "To be." The English Bible translates it as "LORD," which distinguishes it from "Lord" (which is translated as "master").
It is no coincidence that Jesus' name is Yeshua, Hebrew for “Yahweh Saves.” And with that name, Jesus declared that He is also Yahweh Elohim Yeshua. In a divinely timed exchange with Peter, He asked a simply question, “Who do you say I am?”
In the New Testament, in Luke 1:31 an angel tells Mary to name her child Jesus, and in Matthew 1:21 an angel tells Joseph to name the child Jesus during Joseph's first dream.
So why do we call the Hebrew hero of Jericho Joshua and the Christian Messiah Jesus? Because the New Testament was originally written in Greek, not Hebrew or Aramaic. Greeks did not use the sound sh, so the evangelists substituted an S sound. Then, to make it a masculine name, they added another S sound at the end.
Observant Jews and those who follow Talmudic Jewish traditions do not pronounce יהוה nor do they read aloud proposed transcription forms such as Yahweh or Yehovah; instead they replace it with a different term, whether in addressing or referring to the God of Israel.
Though Muslims and Christians can describe Allah and Yahweh in similar ways at times, they are not the same god.
Towards the end of the Babylonian captivity, the very existence of foreign gods was denied, and Yahweh was proclaimed as the creator of the cosmos and the one true God of all the world, giving birth to Judaism, which has c. 14–15 million adherents today.
Jehovah, artificial Latinized rendering of the name of the God of Israel. The name arose among Christians in the Middle Ages through the combination of the consonants YHWH (JHVH) with the vowels of Adonai (“My Lord”).
Most religious scholars and historians agree with Pope Francis that the historical Jesus principally spoke a Galilean dialect of Aramaic. Through trade, invasions and conquest, the Aramaic language had spread far afield by the 7th century B.C., and would become the lingua franca in much of the Middle East.
KAULA LUMPUR, Malaysia — The name of God is sacred to Muslims, and the Arabic word for God, “Allah,” is universally invoked in Islamic prayers and practices.
The Apostle John gives us Jesus' last words (John 19:30), but Matthew, Mark and Luke tell us Jesus cried with a loud voice (Matt. 27:50; Mark 15:37 and Luke 23:46). Jesus also said, “Father, into your hands, I commit my spirit” (Luke 23:46).
Just before he breathed his last breath, Jesus uttered the phrase “it is finished.” Jesus knew that his mission was now finished, and to fulfill Scripture he said, “I am thirsty.” A jar of sour wine was sitting there, so they soaked a sponge in it, put it on a hyssop branch, and held it up to his lips.
Several scholars have argued that the modern precision of marking the time of day should not be read back into the gospel accounts, written at a time when no standardization of timepieces, or exact recording of hours and minutes was available, and time was often approximated to the closest three-hour period.
