Isaiah 63:4

The Warrior continued to explain that this treading judgment was in order that redemption might come. The day of vengeance had arrived, and He had finally punished evildoers (cf. Isaiah 61:2). His bloody victory was not due to a temper out of control but was part of the plan of God.

"The work of redemption was accomplished in chapter 53, but from Isaiah 56:1 onwards the people were called to wait for the promised salvation. The ensuing chapters reveal the need to be rescued from a stressful and hostile environment and from the plague of sin and failure (Isaiah 57:1 ff.; Isaiah 58:1 to Isaiah 59:13). Thus, when the Anointed One acts as mighty to save (1) and when the ’day of my redeemed’ has come, the burden of the activity is the exaction of final vengeance on every foe." [Note: Motyer, p. 511.]
