Psalms 30:6,7 - Joseph Benson’s Commentary on the Old and New Testaments

In my prosperity I said, I shall never be moved I thought myself past all danger of further changes. The word שׁלוי, shalvi, rendered prosperity, denotes peace and tranquillity, arising from an affluent, prosperous condition. When God had settled him quietly on the throne, he thought his troubles were over, and that he should enjoy uninterrupted happiness; that God had placed him secure from all dangers, as though he had taken refuge in an inaccessible mountain, that he had made his prosperity firm, and no more subject to alteration than a mountain is liable to be removed out of its place. By thy favour thou hast made my mountain to stand strong Thou hast firmly settled me in my kingdom, which he calls his mountain, 1st, Because kingdoms are usually called mountains in the prophetical writings, a mountain, by its height, being a very natural representation of a superior condition. 2d, With allusion to mount Zion, the fortress of which he had lately taken, which was properly his mountain, as he had fixed upon it for his dwelling, and had there built his royal palace. All this he regarded as the effect of God's favour to him, and promised himself that his peace and happiness, for the future, would be as undisturbed and unshaken as mount Zion itself. Thou didst hide thy face Displeased with my presumption, and the security I had fondly promised myself, thou didst withdraw thy favour, protection, and help; and I was troubled My dream of uninterrupted tranquillity vanished; I was quickly brought into fresh troubles, difficulties, and dangers, and saw the vanity of all my carnal confidences. Dr. Chandler thinks he refers to the two invasions of the Philistines, which happened soon after they found he had been anointed king over Israel, 2 Samuel 5:17. But, perhaps, he speaks chiefly, if not only, of distress of mind arising from a sense of God's withdrawing the light of his countenance, and showing that he was displeased with him. In this unexpected distress he cried unto the Lord, and in his supplication expressed himself as in the following verses.
