Imagery has a way of fixing an idea in our minds with clarity. In prose we might say with some accuracy: "God meets all our needs and protects us." It is true, but not particularly memorable.
The second -- or sometimes third line -- reinforces and extends the meaning of the first, like a second wave that mounts higher than the first, and a third even higher yet (for example, Psalms 92:9; 93:3; 1).
