Isaiah, whose name means “Yahweh is salvation,” is best known for writing the book that bears his name in the Old Testament. His writings are especially significant for the prophecies he made about the coming Messiah, hundreds of years before Jesus was born (Isaiah 7:14; 9:1-7, 11:2-4; 53:4-7, 9, 12). Matthew quotes Isaiah when describing John the Baptist’s ministry (Matthew 3:3; Isaiah 40:3), and when Jesus moved to Galilee to start His ministry, Isaiah’s prophecy was fulfilled (Matthew 4:13-16; Isaiah 9:1-2).
