The comparison of present national evils with former happiness naturally suggests such questions. Obviously, the casting off spoken of in ver. 7 is that of the nation, and hence its mention confirms the view that the psalmist is suffering under public calamities. All the questions mean substantially one thing--has God changed? They are not, as some questions are, the strongest mode of asserting their negative; nor are they, like others, a more than half assertion of their affirmative; but they are what they purport to be--the anxious interrogations of an afflicted man, who would fain be sure that God is the same as ever, but is staggered by the dismal contrast of Now and Then. He faces with trembling the terrible possibilities, and, however his language may seem to regard failure of resources or fickleness of purpose or limitations in long-suffering as conceivable in God, his doubts are better put into plain speech than lying diffused and darkening, like poisonous mists, in his heart. A thought, be it good or bad, can be dealt with when it is made articulate. Formulating vague conceptions is like cutting a channel in a bog for the water to run. One gets it together in manageable shape, and the soil is drained. So the end of the despondent half of the psalm is marked by the bringing to distinct speech of the suspicions which floated in the singer's mind and made him miserable. The Selah bids us dwell on the questions, so as to realise their gravity and prepare ourselves for their answer.
The second part begins in ver. 10 with an obscure and much-commented-on verse, of which two explanations are possible, depending mainly on the meanings of the two words "sickness" and "years." The former word may mean "my wounding" or "my sickness." The latter is by many commentators taken to be an infinitive verb, with the signification _to be changed_, and by others to be a plural noun meaning "_years_," as in ver. 6. Neglecting some minor differences, we may say that those who understand the word to mean _being changed_ explain the whole thus: "This is my wound (misery, sorrow), that the right hand of the Most High has changed." So the old versions, and Hupfeld, Perowne, and Baethgen. But the use of the word in ver. 6 for "years" creates a strong presumption that its sense is the same here. As to the other word, its force is best seen by reference to a closely parallel passage in Jer. x. 19--"I said, Truly this is my grief (margin, _sickness_), and I must bear it"; where the word for _grief_, though not the same as in the psalm, is cognate. The most probable meaning, then, for the expression here is, "This my affliction is sent from God, and I must bear it with resignation." Then follows an elevating thought expressed in its simplest form like an exclamation, "_the years_," etc.--_i.e.,_, "I will remember (comp. ver. 6) the time when the right hand of Jehovah had the pre-eminence" (Cheyne, _in loc._). Delitzsch leaves the ellipsis unfilled, and takes the whole to mean that the psalmist says to himself that the affliction allotted will only last for the time which the mighty hand of God has determined. The rendering adopted above avoids the awkwardness of using the same word in two different senses in the same context, yields an appropriate meaning, especially in view of the continual references to remembering, and begins the new strophe with a new note of hopefulness, whereas the other renderings prolong the minor key of the first part into the second. It is therefore to be preferred. The revolution in feeling is abrupt. All is sunny and bright in the last half. What makes the change? The recognition of two great truths: first, that the calamity is laid on Israel, and on the psalmist as a member of the nation, by God, and has not come because of that impossible change in Him which the bitter questions had suggested; and, second, the unchangeable eternity of God's delivering power. That second truth comes to him as with a flash, and the broken words of ver. 10 _b_ hail the sudden rising of the new star.
