Isaiah 63:9

“In all their affliction he was afflicted, &c.] That is, God, who said the above words; not properly speaking; for to be afflicted is not consistent with his nature and perfections, being a spirit, and impassible; nor with his infinite and complete happiness; but this is said after the manner of men, and is expressive of the sympathy of God with his afflicted people, and his tender care of them, and concern for them under affliction, as one friend may have for another: afflictions belong to the people of God; they come to them, not by chance, but according to the will of God; and are not in wrath, but in love; they are many and various; there is an “all” of them, yet not one too many, and in…”

“he was afflicted--English Version reads the Hebrew as the Keri (Margin), does, "There was affliction to Him." But the Chetib (text) reads, "There was no affliction" (the change in Hebrew being only of one letter); that is, "In all their affliction there was no (utterly overwhelming) affliction" [GESENIUS]; or, for "Hardly had an affliction befallen them, when the angel of His presence saved them" [MAURER]; or, as best suits the parallelism, "In all their straits there was no straitness in His goodness to them" [HOUBIGANT], (Jdg 10:16; Mic 2:7; Co2 6:12). angel of his presence--literally, "of His face," that is, who stands before Him continually; Messiah (Exo 14:19; Exo 23:20-21; Pro 8:30),…”

“In all their affliction he was afflicted - This is a most beautiful sentiment, meaning that God sympathized with them in all their trials, and that he was ever ready to aid them. This sentiment accords well with the connection; but there has been some doubt whether this is the meaning of the Hebrew. Lowth renders it, as has been already remarked, ‘It was not an envoy, nor an angel of his presence that saved him.’ Noyes, ‘In all their straits they had no distress.’ TheSeptuagint renders it, ‘It was not an ambassador (ου ̓ πρέσβυς ou presbus), nor an angel (οὐδὲ ἄγγελος oude angelos), but he himself saved them.’ Instead of the present Hebrew word (צר tsâr, ‘affliction’), they evidently…”

“The angel - The same that conducted them through the wilderness; the Lord Jesus Christ, who appeared to Moses in the bush. Saved them - From the house of bondage. Carried - He carried them in the arms of his power, and on the wings of his providence. And he is said to do it of old, To remember his ancient kindness for many generations past. Isaiah 63:11”

“63:9 he also suffered: God identified with his suffering people, and their suffering brought him grief. Later, Jesus suffered on behalf of all humanity. • and he personally rescued them: e.g., see Exod 12:25-33; 14:10-31; 23:20-23.”

“all their: Exo 3:7-9; Jdg 10:16; Zac 2:8; Mat 25:40, Mat 25:45; Act 9:4; Heb 2:18, Heb 4:15 the angel: Gen 22:11-17, Gen 48:16; Exo 14:19, Exo 23:20, Exo 23:21, Exo 33:14; Hos 1:7, Hos 12:3-5; Mal 3:1; Act 7:30-32, Act 7:34, Act 7:35, Act 7:38, Act 12:11; Co1 10:9 in his: Deu 7:7, Deu 7:8; Psa 78:38, Psa 106:7-10; Tit 2:14; Jo1 4:9, Jo1 4:10; Rev 1:5, Rev 5:9 carried: Isa 46:3, Isa 46:4; Exo 19:4; Deu 1:31, Deu 32:11, Deu 32:12; Luk 15:5 Isaiah 63:10”

“The next v. commemorates the way in which He proved Himself a Saviour in heart and action. "In all their affliction He was afflicted, and the Angel of His face brought them salvation. In His love and in His pity He redeemed them, and lifted them up, and bare them all the days of the olden time." This is one of the fifteen passages in which the chethib has לא, the keri לו. It is only with difficulty that we can obtain any meaning from the chethib: "in all the affliction which He brought upon them He did not afflict, viz., according to their desert" (Targ., Jer., Rashi); or better still, as tsâr must in this case be derived from tsūr, and tsăr is only met with in an intransitive sense, "In…”
