Isaiah 42:6

Yahweh not only called an invader in harmony with His righteous purposes for humankind (Isaiah 41:2), but He alone also called this Servant at the right time, in the right place, and for the right purpose.

"The righteousness of God is the stringency with which He acts, in accordance with the will of His holiness." [Note: Delitzsch, 2:178.]

Cyrus would destroy, but Messiah would build. The Lord promised again to uphold His Servant (cf. Isaiah 42:1). The Servant would fulfill the covenant requirements and promises that God had given His people, becoming a covenant to them in that sense, and so bring them into intimate fellowship with Himself (cf. Isaiah 49:6-8). Thus this Servant cannot be all of Israel or even saved Israel or the prophets. Some commentators view this covenant as the New Covenant (Jeremiah 31:31-34), which Christ would ratify with His blood. [Note: See Ibid., 179-80; Grogan, p. 255; and Chisholm, Handbook on . . ., p. 100-101.] Still others view it as the "covenant of grace" that Christ made available to people by dying on the Cross. [Note: See Young, 3:120-21.] The coming conqueror would drive the nations further into idolatry (Isaiah 41:5-7), but the Servant would lead them to God by serving as a light to the nations who sit in darkness (cf. Luke 2:32; John 14:6). The Lord Himself would do all this through His Servant (cf. Exodus 3:15; Exodus 6:3).
