Isaiah 63:9

9. In all their affliction he was afflicted Was a sharer in “their affliction,” and consequently not the inflicter, or, he was not one who afflicted. The original well bears either meaning. The difference arises by לא , not, in the Hebrew text, and לו , for him, in the margin. Original copies vary on these two forms. To general readers the difference is not essential, and scarcely important.

Angel of his presence (See Exodus 23:20-21; Numbers 20:16.) This means the “angel” standing in his presence. In Old Testament theophanies, the Servant, or Messenger in other words, the Messiah, often appeared in bodily form to his people or their representatives. The remaining words tenderly express the divine interferences for God’s ancient saints.
