2:2 rock. As a metaphor for God, this term is concentrated in poetic passages such as the song of Moses in Deut. 32; the song of David in 2 Sam. 22; Psalms; and Isaiah. The metaphor suggests God’s strength and sovereignty, and the security of those who trust in Him. Here the focus is on the uniqueness of the one true God as opposed to false sources of security (compare the contrast with false gods, also called “rock,” in Deut. 32:31, 37; Is. 44:8).
