Isaiah 53:11

After His sacrificial work had ended, the Servant would look back on it with satisfaction, as would Yahweh (cf. 1 John 2:2). The "many" would obtain justification through the knowledge of Him and His work. The "many" is a distinct group, numerous but not all-inclusive, namely: believers. No other work is required but believing what one comes to know, namely: to rely on Him and His work. It is possible that Isaiah meant that the Servant alone would possess knowledge regarding what God required in relation to sin and what He should do about that, but this seems unlikely. One scholar argued that it was the Servant’s knowledge of God, and of God’s unfolding purpose for the peoples of the world, that satisfied Him and ultimately made many righteous. [Note: James M. Ward, "The Servant’s Knowledge in Isaiah 40-55," in Israelite Wisdom: Theological and Literary Essays in Honor of Samuel Terrien, pp. 129, 135.] The one Righteous Servant would make many people righteous by bearing their iniquities, not His own (cf. Isaiah 53:4-6; John 10:14-18; Romans 5:18-19). As Cyrus was God’s anointed servant to restore the Israelites to their land, so the Servant would be God’s anointed Servant to restore humanity to Himself. He would accomplish what the Old Covenant sacrificial system prefigured and anticipated.
