The Lord Saves
"Jesus" is the English form of the much-older Greek name (pronounced) ee-ay-soos (the New Testament was written mostly in Greek). The older Greek name itself originated from the even-older Hebrew name (The Older Testament was written mostly in Hebrew) pronounced yeh-ho-shoo-ah, or "Joshua," which means "The Lord saves." Jesus was the Christ ("Christ" is from the Greek word pronounced cris-tose, meaning Anointed One) but His name, according to custom, was (transliterated from Hebrew) Yeh-ho-shoo-ah ben Yoe-safe, meaning "Joshua son of Joseph" ("ben" means son of). In the greater family sense (i.e. like when someone named Smith is as much genetically entitled to go to a Jones family reunion if that Smith is as much an actual descendant of a common Jones ancestor as the others who happen to have the Jones name), Jesus of Nazareth (see Nazarene) was also named Yeh-ho-shoo-ah ben Daw-veed, or Joshua son of David.
"We have found him, of whom Moses in the Law, and the prophets, did write, Jesus of Nazareth, the son of Joseph." (John 1:45 KJV)
"And the multitudes that went before, and that followed, cried, saying, Hosanna to the son of David: Blessed is He that cometh in the Name of The Lord; Hosanna in the highest." (Matthew 21:9 KJV)
"He bare the sin of many, and made intercession for the transgressors"
It's amazing (amazing how anyone can deny it, that is) how Jesus was so plainly and accurately described far back in the Old Testament (e.g. see The Messianic Psalms and First And Second Comings In Isaiah). The Hebrew Scriptures have abundant descriptions of a man who only Jesus of Nazareth fulfilled, such as this example from Isaiah that identifies His life, death and purpose.
"For he shall grow up before him as a tender plant, and as a root [again, see Nazarene] out of a dry ground: he hath no form nor comeliness; and when we shall see him, there is no beauty that we should desire him." [see What Did Jesus Look Like?]
"He is despised and rejected of men; a man of sorrows, and acquainted with grief: and we hid as it were our faces from him; he was despised, and we esteemed him not. Surely he hath borne our griefs, and carried our sorrows: yet we did esteem him stricken, smitten of God [see Eloi, Eloi, Lama Sabachthani?], and afflicted."
"But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed." [see also What Did Christ's Cross Really Look Like?]
"All we like sheep have gone astray; we have turned every one to his own way; and The Lord hath laid on him the iniquity of us all. He was oppressed, and he was afflicted, yet he opened not his mouth: he is brought as a lamb to the slaughter [see Passover and The Lamb Of God], and as a sheep before her shearers is dumb, so he openeth not his mouth."
"He was taken from prison and from judgment: and who shall declare his generation? for he was cut off out of the land of the living: for the transgression of my people was he stricken. And he made his grave [see The Garden Tomb; also Shroud Of Turin: A Miraculous Fake?] with the wicked, and with the rich in his death; because he had done no violence, neither was any deceit in his mouth."
"Yet it pleased The Lord to bruise him; he hath put him to grief: when thou shalt make his soul [see Where Is Your Soul?] an offering for sin, he shall see his seed, he shall prolong his days, and the pleasure of The Lord shall prosper in his hand. He shall see of the travail of his soul, and shall be satisfied: by his knowledge shall my righteous servant justify many; for he shall bear their iniquities."
"Therefore will I divide him a portion with the great, and he shall divide the spoil with the strong; because he hath poured out his soul unto death: and he was numbered with the transgressors; and he bare the sin of many, and made intercession [see What Is Jesus Christ Doing Right Now?] for the transgressors." (Isaiah 53:2-12 KJV)
