Psalms 57:8

Hence--he addresses his glory, or tongue (Ps 16:9; 30:12), and his psaltery, or lute, and harp. I myself . . . early--literally, "I will awaken dawn," poetically expressing his zeal and diligence.

Awake up, my glory. Let the noblest powers of my nature bestir themselves: the intellect which conceives thought, the tongue which expresses it, and the inspired imagination which beautifies it—let all be on the alert now that the hour for praise has come. Awake, psaltery and harp. Let all the music with which I am familiar be well attuned for the hallowed service of praise. I myself will awake early. I will awake the dawn with my joyous notes. No sleepy verses and weary notes shall be heard from me; I will thoroughly arouse myself for this high employ. When we are at our best we fall short of the Lord's deserts, let us, therefore, make sure that what we bring him is our best, and, if marred with infirmity, at least let it not be deteriorated by indolence. Three times the psalmist calls upon himself to awake. Do we need so much arousing, and for such work? Then let us not spare it, for the engagement is too honourable, too needful to be left undone or ill done for want of arousing ourselves.

Awake up, my glory - Instead of כבודי kebodi, “my glory,” one MS., and the Syriac, have כנורי kinnori, “my harp.” Dr. Kennicott reads כבורי kebori, which he supposes to be some instrument of music; and adds that the instrument used in church-music by the Ethiopians is now called כבר kaber. I think the Syriac likely to be the true reading: “Awake up, my harp; awake, psaltery and harp: I will awake early.” Such repetitions are frequent in the Hebrew poets. If we read my glory, it may refer either to his tongue; or, which is more likely, to his skill in composition, and in playing on differentt instruments. The five last verses of this Psalm are nearly the same with the Psa 108:1-5 of Psa 108:1-13. The reason of this may be, the notes or memoranda from the psalmist’s diary were probably, through mistake, twice copied. The insertion at the beginning of the 108th Psalm seems to bear no relation to the rest of that ode. Rabbi Solomon Jarchi tells us that David had a harp at his bed’s head, which played of itself when the north wind blew on it; and then David arose to give praise to God. This account has been treated as a ridiculous fable by grave Christian writers. I would however hesitate, and ask one question: Does not the account itself point out an instrument then well known, similar to the comparatively lately discovered Aeolian harp? Was not this the instrument hung at David’s bed’s head, which, when the night breeze (which probably blew at a certain time) began to act upon the cords, sent forth those dulcet, those heavenly sounds, for which the Aeolian harp is remarkable? “Awake, my harp, at the due time: I will not wait for thee now, I have the strongest cause for gratitude; I will awake earlier than usual to sing the praises of my God.”

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. Awake, psaltery and harp - In regard to these instruments, see the notes at Isa 5:12. The instrument denoted by the word “psaltery” - נבל nebel - was a stringed instrument, usually with twelve strings, and played with the fingers. See the notes at Psa 33:2. The “harp” or “lyre” - כנור kinnôr - was also a stringed instrument, usually consisting of ten strings. Josephus says that it was struck or played with a key. From 1Sa 16:23; 1Sa 18:10; 1Sa 19:9, it appears, however, that it was sometimes played with the fingers. I myself will awake early - That is, I will awake early in the morning to praise God; I will arouse myself from slumber to do this; I will devote the first moments - the early morning - to his worship. These words do not imply that this was an evening psalm, and that he would awake on the morrow - the next day - to praise God; but they refer to what he intended should be his general habit - that he would devote the early morning (arousing himself for that purpose) to the praise of God.
