Final answer:
In Luke, Jesus read from the book of Isaiah when he read from the scroll in the synagogue in Nazareth.
Step-by-step explanation:
When Jesus read from the scroll in Luke, he read from the book of Isaiah. In Luke 4:16-21, Jesus enters the synagogue in Nazareth and is handed the scroll of the prophet Isaiah. He opens it to a passage that is now known to correspond with Isaiah 61:1-2, and after reading it, he begins to say, "Today this Scripture has been fulfilled in your hearing." This moment is significant, as Jesus reveals his mission and identity as the one whom Isaiah spoke about, bringing good news to the poor and proclaiming liberty to the captives.
