Matt 1:21 "And she shall bring forth a son, and thou shalt call his name JESUS: for he shall save his people from their sins."
The Bible said:
"And she shall bring forth a son, and thou shalt call his name JESUS: for he shall save his people from their sins." (Matthew 1:21).
He shall be called JESUS because he shall save his people from their sins.
It is interesting that the King James Cambridge Edition (circa 1900) has the words Jesus capitalized (JESUS). I believe this is fitting. An emphasis on the one who would be our Savior. It's beautiful. For who would not want to emphasize the first mention of the name of our Savior?
"Jesus" is an Anglicized form of the Greek name "Yesous" found in the New Testament. Yesous represents the Hebrew Bible name "Yeshua," which occurs as "Jeshua" in English Bibles (Ezra 2:2; Nehemiah 7:7). In Medieval English the "J" was pronounced as a "Y."
"Yehoshua"
Yeshua, in turn, is a shortened form of the name Yehoshua ("Joshua" in English Bibles).
"Yehoshua" is a compound name consisting of two elements.
(1) The prefix "Yeho–" is an abbreviation of the Tetragrammaton, God's Four-Letter Name: Yod-He-Vav-He:
YHVH. (Modern scholars think the third letter was pronounced as "W." Thus: YHWH, Yahweh.)
The 4-Letter Name
The "Name" YHVH is used over 6,800 times in the Hebrew Bible.
In the Hebrew Bible
"Yeho-" is a prefix form of God's name.
The second element of the name
Yeho–shua is a form of the Hebrew verb
yasha which means to deliver, save, or rescue.
Thus, linguistically, the name "Yehoshua—Yeshua—Jesus" conveys the idea that God (YHVH) delivers, saves, rescues — eventually through his servant Messiah, who bears God's name.
The Hebrew Bible word "savior" [moshiah] is also rooted to
yasha.
Moshiah is used 9x for God (2 Samuel 22:3; Isaiah 43:3; Isaiah 45:15, Isaiah 45:21; Isaiah 49:26; Isaiah 60:16; Isaiah 63:8; Jeremiah 14:8; Hosea 13:4). It's used 5x for human "deliverers," "rescuers" or "saviors" (Judges 3:9, Judges 3:15; 2 Kings 13:5; Obadiah 1:21; Nehemiah 9:27).
This is how the name "Jesus" would have been written in ancient Hebrew documents. The four letters or consonants from right to left are Yod, Shin, Vav, Ayin (Y, SH, OO, A). Jesus is the Greek name for the Hebrew name Joshua or Y'shua which means "The LORD or Yahweh is Salvation".
And this is Jesus's name (or Yeshua's name) in Modern Hebrew:
