Barnes' Notes
He only is my rock ... - See the notes at Psalms 62:2. The only difference between this verse and Psalms 62:2 is, that in this verse the word "greatly" is omitted. The psalmist declares here in the most absolute manner, that he shall not be "moved" at all. In Psalms 62:2, he said that he would not be "greatly moved;" his mind would not be much or materially disturbed. The language here indicates more entire confidence - more certain conviction - showing that the slight apprehension or fear which existed in the beginning of the psalm, had been wholly dissipated, and that his mind had become perfectly calm.
