[63:4] 1 tn Heb “for the day of vengeance was in my heart, and the year of my revenge came.” The term גְּאוּלַי (gÿ’ulai) is sometimes translated here “my redemption,” for the verbal root גאל often means “deliver, buy back.” A גֹּאֵל (go’el, “kinsman-redeemer”) was responsible for protecting the extended family’s interests, often by redeeming property that had been sold outside the family. However, the responsibilities of a גֹּאֵל extended beyond financial concerns. He was also responsible for avenging the shed blood of a family member (see Num 35:19-27; Deut 19:6-12). In Isa 63:4, where vengeance is a prominent theme (note the previous line), it is probably this function of the family protector that is in view. The Lord pictures himself as a blood avenger who waits for the day of vengeance to arrive and then springs into action.
[63:5] 2 sn See Isa 59:16 for similar language.
[63:5] 3 tn Heb “and my anger, it supported me”; NIV “my own wrath sustained me.”
