I remembered God, and was troubled,.... Either the mercy, grace, and goodness of God, as Jarchi; how ungrateful he had been to him, how sadly he had requited him, how unthankful and unholy he was, notwithstanding so much kindness; and when he called this to mind it troubled him; or when he remembered the grace and goodness of God to him in time past, and how it was with him now, that it was not with him as then; this gave him uneasiness, and set him a praying and crying, that it might be with him as heretofore, Job 29:2, or rather he remembered the greatness and majesty of God, his power and his justice, his purity and holiness, and himself as a worm, a poor weak creature, sinful dust and ashes, not able to stand before him; he considered him not as his father and friend, but as an angry Judge, incensed against him, and demanding satisfaction of him: I complained; of sin and sorrow, of affliction and distress: or "I prayed", or "meditated" (l); he thought on his case, and prayed over it, and poured out his complaint unto God, yet found no relief: and my spirit was overwhelmed; covered with grief and sorrow, pressed down with affliction, ready to sink and faint under it: Selah: See Gill on Psa 3:2.
