(7) Lord, by thy favour--i.e., and all the while thou (not my own strength) hadst made me secure. The margin gives the literal rendering, but the reading varies between the text "to my mountain," "to my honour" (LXX., Vulg., and Syriac), and "on mountains," the last involving the supply of the pronoun "me." The sense, however, is the same, and is obvious. The mountain of strength, perhaps mountain fortress, is an image of secure retreat. Doubtless Mount Zion was in the poet's thought.

Thou didst . . .--The fluctuation of feeling is well shown by the rapid succession of clauses without any connecting conjunctions.

Verse 7. - Lord, by thy favour thou hast (rather, hadst) made my mountain to stand strong. It was thy favour which had given me the "prosperity" whereby I was exalted, and which I thought rooted in myself - which had made Zion strong, and enabled me to triumph over my enemies. But, lo! suddenly all was changed - Thou didst hide thy face, and I was troubled. God turned his face away, declared himself angry with his servant (1 Chronicles 21:7-12), and sent the dreadful plague which in a single day destroyed seventy thousand lives. Then David, feeling that God's face was indeed turned from him, "was troubled."

30:6-12 When things are well with us, we are very apt to think that they will always be so. When we see our mistake, it becomes us to think with shame upon our carnal security as our folly. If God hide his face, a good man is troubled, though no other calamity befal him. But if God, in wisdom and justice, turn from us, it will be the greatest folly if we turn from him. No; let us learn to pray in the dark. The sanctified spirit, which returns to God, shall praise him, shall be still praising him; but the services of God's house cannot be performed by the dust; it cannot praise him; there is none of that device or working in the grave, for it is the land of silence. We ask aright for life, when we do so that we may live to praise him. In due time God delivered the psalmist out of his troubles. Our tongue is our glory, and never more so than when employed in praising God. He would persevere to the end in praise, hoping that he should shortly be where this would be the everlasting work. But let all beware of carnal security. Neither outward prosperity, nor inward peace, here, are sure and lasting. The Lord, in his favour, has fixed the believer's safety firm as the deep-rooted mountains, but he must expect to meet with temptations and afflictions. When we grow careless, we fall into sin, the Lord hides his face, our comforts droop, and troubles assail us.Lord, by thy favour thou hast made my mountain to stand strong,.... The psalmist found himself mistaken, and acknowledges it; that as it was not owing to his own merit that he enjoyed the prosperity that he did, so neither was the continuance of it owing to his goodness, power, and strength, but to the free grace and favour of God; as the church of God is compared to a mountain, and the several individuals of believers are like to Mount Zion, so the soul of a child of God may be called his mountain, which is made strong by the Lord as to its state in Christ, being set on him, the Rock of ages, and sure foundation, where it is safe and secure; and as to its grace, whenever it is in any strong exercise, which is altogether owing to the favour of God, and continues as long as he pleases;

thou didst hide thy face, and I was troubled; the Lord may hide his face from his people, and yet their state be safe; their mountain stands strong in that respect; yet this generally produces a change of frames; it gives trouble, and faith and hope become feeble and languid in their acts and exercises; this shows the changeableness of frames, that they are not to be depended upon; that they are entirely owing to the pleasure of God, and that rejoicing only should be in him: very likely some regard is had to the affair of Absalom's rebellion, which came unawares, unthought of, when David was in the greatest prosperity and security.
