Psalms 77:10

“And I said, this is my infirmity, etc.] Referring either to what he had said in the preceding verses; and which is to be considered either as checking and correcting himself for what he had said, and acknowledging his evil in it; and it is as if he had said, this is a sin against God, that I am guilty of in questioning his love, and disbelieving his promises; it is an iniquity I am prone unto, a sin that easily besets me; it flows from the corruption of my nature, and the plague of my heart, and shows a distempered mind; it is owing to the weakness of my faith and judgment; I have said this rashly, and in haste, without well weighing and considering things, and I am sorry for it, I will stop…”

“And I said, This is my infirmity - The meaning of this phrase is not, as would appear from our translation, that his reflections on the subject were to be traced to his weakness, or were a proof of weakness of mind, but that the subject overpowered him. This verse has been very variously rendered. The Septuagint and the Vulgate translate it, “And I said, now I begin; this is a change of the right hand of the Most High,” with what meaning it is difficult to see. Luther renders it, “But yet I said, I must suffer this; the right hand of the Most High can change all;” a beautiful sentiment, but probably not the idea in the original. The Hebrew means, “This makes me sick;” that is, “This…”

“I said - These suspicions of God's faithfulness proceed from the weakness of my faith. The years - The years wherein God hath done great and glorious works, which are often ascribed to God's right - hand. Psalms 77:13”

“77:10-12 The memories of God’s mighty works in the past fill the psalmist’s mind. 77:10 The psalmist fears that God’s hand of protection (44:3; 77:15; Exod 6:6) and favor (Pss 16:7-8; 110:1) is now against him for no apparent reason.”

“This is: etc. Or, as Dr. Waterland renders, "This my affliction is a change of the right hand of the Most High," i.e., it proceeds from a change of God's conduct towards me. De Dieu renders, Precari, hoc meum est; mutare dextram Altissimì "To pray, this is my business. to change the right hand of the Most High." I can do nothing else than pray: God is the Ruler of events. Mr. N. M. Berlin translates, Dolere meum hoc est: mutare est dextre Altissimi. "To grieve is my portion. to change (my condition) belongs to the right hand of the Most High." Psa 31:22, Psa 73:22, Psa 116:11; Job 42:3; Lam 3:18-23; Mar 9:24 the years: Psa 77:5; Exo 15:6; Num 23:21, Num 23:22; Deu 4:34; Hab 3:2-13 Psalms…”

“With ואמר the poet introduces the self-encouragement with which he has hitherto calmed himself when such questions of temptation were wont to intrude themselves upon him, and with which he still soothes himself. In the rendering of הלּותי (with the tone regularly drawn back before the following monosyllable) even the Targum wavers between מרעוּתי (my affliction) and בּעוּתי (my supplication); and just in the same way, in the rendering of Psa 77:11, between אשׁתּניו (have changed) and שׁנין (years). שׁנות cannot possibly signify "change" in an active sense, as Luther renders: "The right hand of the Most High can change everything," but only a having become different (lxx and the Quinta…”
