General Information:

David continues his song to Yahweh.

He makes my feet swift like a deer and places me on the high hills

Here David's feet are compared to those of a deer using exaggeration. Yahweh gives David the strength to move quickly and provides secure places for protection and rest. (See: rc://en/ta/man/jit/figs-simile and rc://en/ta/man/jit/figs-hyperbole)
