His name isn’t really “Jesus”....it’s Yeshua. Yeshua means salvation.....”Jesus” doesn’t have a meaning. When the gosple spread to hellenized world they changed the Y at the beginning to a J. The hebrew ending “ah” sound did not go over well for Greeks because that was how they ended feminine names. So they gave it a greek masculine ending with an “s”. Notice a lot of greco-roman names end this way (Persius,Onesimus, Julius)....
Oh yes it is.
Matthew 1:21 And she shall bring forth a son, and thou shalt call his name JESUS (Iēsoun): for he shall save his people from their sins.
Luke1:31 And, behold, thou shalt conceive in thy womb, and bring forth a son, and shalt call his name JESUS (Iēsoun).
Iésous - 2424 Iēsoús – Jesus, the transliteration of the Hebrew term, 3091 /Lṓt ("Yehoshua"/Jehoshua, contracted to "Joshua") which means "Yahweh saves" (or "Yahweh is salvation"). [http://biblehub.com/greek/2424.htm]
