Who Was Isaiah In The Bible
The short answer
Isaiah was a prophet in Jerusalem in the eighth century BC, speaking to kings and crowds during a dangerous stretch of Judah's history, when the Assyrian empire loomed over the small kingdoms of the region. The book that bears his name is one of the longest in the Bible, and it ranges from stern warnings about injustice to some of the most tender promises of comfort in all of scripture. But to answer the question of who Isaiah really was, you have to look at what he saw and how he chose to say it.
What he saw, especially in the great central section of the book (chapters 40–55), was a figure often called the servant of the Lord — someone anointed by God who would suffer and die not for his own failures but for the sins of Israel and the wider world. The fourth of the so-called servant songs, Isaiah 53, describes this redeeming death with astonishing gratitude and awe. According to N. T. Wright's reading of Mark's gospel, this was the passage Jesus himself returned to when he warned his disciples about his coming death. In other words, Isaiah didn't just predict a distant future; his words became something like a script that Jesus consciously took up as his own vocation.
How Isaiah said it matters just as much. He often spoke of the sun going dark, the moon failing, the stars falling. As Wright points out, first-century readers knew this wasn't astronomy — it was well-established code for enormous social and political upheaval, the way we say empires "fall" without imagining physical movement. Miss that, and you misread Isaiah. Grasp it, and you meet a poet-prophet whose vivid language about collapsing powers and a suffering servant reshaped how an entire people — and eventually Jesus — understood God's work in history.
What scholars say
How did Jesus understand his own approaching death? In this excerpt, N. T. Wright shows Jesus returning explicitly to Isaiah's servant — the messianic figure at the heart of Isaiah 40–55 who suffers and dies for the sins of Israel and the world.
“This is the third time Jesus has solemnly warned the disciples about what’s going to happen to him. It isn’t taking him by surprise. It’s part of the vocation which has gripped him since, at least, the voice at his baptism , which echoed Isaiah’s prophecy about the servant, to which in this passage he returns explicitly. The great central section of Isaiah (chapters 40—55) has as its main character, after Israel’s God himself, an anointed, messianic figure who suffers and dies for the sins of Israel and the world. This is ‘ YHWH ’s servant’, and at the end of the passage Jesus refers back to Isaiah 53, the fourth ‘servant song’, which speaks in awe and gratitude of the servant’s redeeming death.”
“For Isaiah, and for those who read him in the first century, the one thing it didn’t mean was something to do with the actual sun, moon and stars in the sky. That would make a quite different tune. This language was well known, regular code for talking about what we would call huge social and political convulsions. When we say that empires ‘fall’, or that kingdoms ‘rise’, we don’t normally envisage any actual downward or upward physical movement. Matthew intends us to understand that the time of the coming of the son of man will be a time when the whole world seems to be in turmoil.”
What it means for you
Isaiah invites you to read the news the way he read his own turbulent times: not as random chaos, but as a world in which God is still at work, often through suffering rather than around it. His servant figure suggests that the deepest kind of strength can look, from the outside, like defeat. If you're facing a season where faithfulness costs you something, Isaiah's vision — and the way Jesus embraced it — reframes that cost as potentially meaningful rather than wasted.
His poetry also teaches a habit of careful reading. Before deciding what a dramatic-sounding Bible passage means, ask what its first hearers would have understood. Often the point is closer to home, and more demanding, than a spectacle in the sky.
In context
The book of Isaiah opens with the prophet's call and his confrontations with Judah's kings in chapters 1–39, set against the Assyrian threat. Chapters 40–55 shift to words of comfort for a people facing exile, and it is here that the servant songs appear, climaxing in Isaiah 53. The final chapters look toward restoration and a renewed creation. New Testament writers quote Isaiah constantly — the gospels present Jesus drawing on the servant passages to explain his own death, which is why Isaiah is sometimes called the fifth gospel.
