Intro to Isaiah

"The name of the prophet, Isaiah, or Jesahiahu (for so it is in the Hebrew), which, in the New Testament is read Esaias. His name signifies the salvation of the Lord - a proper name for a prophet by whom God gives knowledge of salvation to his people, especially for this prophet, who prophesies so much of Jesus the Saviour and of the great salvation wrought out by him."

Matthew Henry
