Psalms 57:8

8.Awake up, my tongue David here expresses, in poetical terms, the ardor with which his soul was inspired. He calls upon tongue, psaltery, and harp, to prepare for the celebration of the name of God. The word כבוד, cabod, which I have translated tongue, some have rendered glory; but although this is its more common signification, it bears the other in the sixteenth psalm, and in numerous places of Scripture. The context proves this to be its signification here, David intimating that he would celebrate the praises of God both with the voice and with instrumental music. He assigns the first place to the heart, the second to declaration with the mouth, the third to such accompaniments as stimulate to greater ardor in the service. It matters little whether we render the verb אעירה, airah, I will be awaked, or transitively, I will awake myself by dawn of day. (345) But one who is really awaked to the exercise of praising God, we are here taught will be unremitting in every part of the duty.

“Oft listening how the hound and horn
Cheerly rouse the slumbering morn.”
