Psalms 57:8

Awake up, my glory -By the word “glory” here some understand the tongue; others understand the soul itself, as the glory of man. The “word” properly refers to that which is weighty, or important; then, anything valuable, splendid, magnificent. Here it seems to refer to all that David regarded as glorious and honorable in himself - his noblest powers of soul - all in him that “could” be employed in the praise of God. The occasion was one on which it was proper to call all his powers into exercise; all that was noble in him as a man. The words “awake up” are equivalent to “arouse;” a solemn appeal to put forth all the powers of the soul.
