John Gill's Exposition of the Whole Bible
Psalms 77:10
And I said, this is my infirmity,.... 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 proceed no further: or else as comforting and encouraging himself in his melancholy circumstances; and the sense is, this is an "infirmity", an affliction and trouble that I am at present exercised with; but it is but a temporal one, it will not always last; I shall get over it, and out of it; it is a sickness, but not to death; and it is "mine", what is allotted to me; every man has his affliction and cross, and this is mine, and I must bear it patiently; see
Jeremiah 10:19, or else this refers to what follows, which some render, "the changes of the right hand of the most High" s; and the meaning may be, this is my affliction and trouble, that there are changes in the right hand of the most High; that is, that that hand which used to be exerted in his favour, and against his enemies, was now withdrawn, and hid in his bosom; see Psalms 74:11, and that which liberally distributed favours to him was now laid upon him in an afflictive way; and to this sense is the Targum,
"this is my infirmity, the change of the power of the right hand (or the powerful right hand) of the most High;''
though another Targum is,
"this is my prayer, c. the years of the end from the right hand''
and Aben Ezra makes mention of some as so interpreting the first clause, to which De Dieu agrees, who renders the whole, "and I said, this is my prayer, that the right hand of the most High might be changed"; that is, that his dispensations of providence might be changed; that he would bring him out of these afflicted, sorrowful, and melancholy circumstances, into a more comfortable one: as these words may be understood as what the psalmist comforted himself with, that there are "changes of the right hand of the most High"; I have been greatly troubled and distressed, and I have been so weak as to call in question the mercy and favour of God, and his promises to me, which I own is my sin; but I have reason to believe it will not be always thus with me, God will take off his hand, it shall not always lie thus heavy upon me; though he cause grief, he will have compassion, and turn again to me; there will be a change, and I will wait till that comes: but Kimchi thinks the word אזכור, "I will remember", which stands at the beginning of the next verse, belongs to that and this; and is to be supplied here, as it is in our translation, and interprets the whole to the like sense;
but I will remember the years of the right hand of the most High; which the psalmist proposed to do as a means to remove his doubts, despondency, and unbelief, and to relieve and strengthen his faith; as that God was the most High in all the earth, and above his enemies; that he had a right hand of power, which in years past had been exerted on the behalf of his people, and on his behalf; which was not impaired and shortened, but the same as ever, and sooner or later would be again used in his favour.
