The Servant in Isaiah

The nation Israel is called the servant:

41:8; 42:19; 43:10; 44:1, 2, 21; 45:4; 48:20

The Messiah is called the Servant:

42:1-17; 49:3, 5-7; 50:10; 52:13; 53:11

The nation was given a mission to serve God, to be custodian of his word, and to be alight to the Gentile nations. Because of sin and rebellion, they failed. God sent his Son, Christ, as Messiah to fulfill his mission on earth.
