He only is my rock - See the notes at Psalm 62:2. The only difference between this verse and Psalm 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 Psalm 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.
He only is my rock and my salvation,.... See Gill on Psalm 62:2;
he is my defence; these epithets of God are repeated, to strengthen his faith and hope in him, and to encourage a patient waiting upon him;
I shall not be moved; neither greatly, nor at all; his faith gets fresh strength and rigour, the more he considers God as his rock, salvation, defence, and refuge; See Gill on Psalm 62:2.
not be moved--not at all; his confidence has increased.
