The book of Isaiah gives us a glimpse of who Jesus is in the Old Testament (O.T).
The book of Isaiah can be likened to an miniature Bible. Like the entire Bible has 66 books, Isaiah has 66 chapters. In the first 39 chapters, Isaiah stresses the RIGHTEOUSNESS, HOLINESS and JUSTICE of God, a theme similar to the 39 books of the Old Testament. In the next 27 chapters of Isaiah portrays the Lord’s GLORY, COMPASSION and GRACE, a theme similar to the 27 books of the New Testament. In the 40+ years it records, it spans 4 kings of Judah. The Book starts with the Judgment of Judah and the nations and in the middle moves into Redemption, closing with Redemption and Future Glory.
Isaiah, the Latin form of Yesha’yahu (shortened as Yeshaiah) means Yahweh is Salvation and the well known passages in Isaiah that we are familiar with are from Isaiah 9:6 and Isaiah 53.
Isaiah 9:6 which is the prophecy of the ANOINTED ONE reads
For unto us a child is born (expressing the humanity of Jesus),
unto us a Son is given (expressing the divinity of Jesus).
And Isaiah 53 which is a prophecy of the ANOINTED ONE’s ATONING WORK states the Jesus was wounded for our transgressions, Bruised for our Iniquities and The chastisement of our peace was upon him and by His stripes, we are healed and like a Lamb to slaughter, He (Jesus) came.
Now when we fast forward many years, we saw John the Baptist, a man dressed brutishly, alongside a river making a promulgation as recorded in John 1:29 (29 The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God (Agnus Dei), which taketh away the sin of the world.)
The Lamb that Isaiah saw being led to the slaughter, is the Lamb of God that John the Baptist sees, and it will be this same Lamb that we will all see, seated on the throne, of whom it will be sung – Blessing and honor, and glory and power be unto him who sits on the throne and unto the Lamb, forever and forever and ever and ever … (Revelation 5:13) and Salvation to our God which sitteth upon the throne, and unto the Lamb. (Revelation 7:10)
In Isaiah, Jesus is the Agnus Dei, The Lamb of God
Isaiah 53: 5-7
5 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.
6 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.
7 He was oppressed, and he was afflicted, yet he opened not his mouth: he is brought as a lamb to the slaughter, and as a sheep before her shearers is dumb, so he openeth not his mouth.
