I laid me down and slept
After the battle was over between Absalom's men and his, says Aben Ezra; but rather this was in the midst of his trouble and distress, since he afterwards prays for salvation: and this sleep was either, as Jarchi observes, through his heart being overwhelmed with grief; for there have been instances of persons sleeping through sorrow, as Elijah, Jonah, and the disciples of Christ, ( 1 Kings 19:4 1 Kings 19:5 ) ( Jonah 1:3 ) ( Luke 22:45 ) ; or rather this is expressive of the calmness and serenity of his mind amidst his troubles; he laid himself down in peace, and slept quietly and comfortably; he did not lose a night's rest, his sleep was sweet unto him; which was a blessing of life from the Lord that everyone does not enjoy; see ( Psalms 127:2 ) ;
in the morning, alive and cheerful, Some lay themselves down and never awake more, as Sisera the captain of Jabin's army, and Ishbosheth the son of Saul; and this might have been David's case, considering the circumstances he was in: and others, through perplexing thoughts and cares, or pains of body, or uneasy dreams, rise fatigued and distressed; but David arose in good health of body, and tranquillity of mind, and comfortably refreshed;
for the Lord sustained me;
the psalmist committed himself to the care and protection of God; he laid himself down in his arms, and there slept in safety; the Lord preserved him, who is Israel's keeper, that neither slumbers nor sleeps: and he rose in health and cheerfulness in the morning, supported by his right hand. This shows, that lying down to sleep, when in such circumstances, and awaking with cheerfulness, were not owing to rashness, stupidity, and insensibility, but to divine supports. These words may be interpreted, as they are by some of the ancients, of the death of Christ, and of his resurrection from the dead by the power of God; death is often expressed by sleep, and the resurrection of the dead by an awaking out of sleep, ( Daniel 12:2 ) ( Isaiah 26:19 ) ; and Christ's death being signified by lying down and sleeping, may denote both the voluntariness of it, that he laid down his life freely and willingly; and his short continuance under the power of death, it was but like a night's sleep; and his resurrection from the dead, being expressed by an awaking through the Lord's sustaining him, shows that it was by the power of God, even the exceeding greatness of his power: and the whole of this may be applied to the case and state of the saints and people of God, who at times have rest and peace amidst their enemies; though they have tribulation in the world, they have peace in Christ; and notwithstanding the temptations of Satan, and the corruptions of their own hearts, they have joy and comfort through believing in Christ; the Lord sustains them with precious promises, and supports them with the discoveries of his love, and upholds them with the right hand of his righteousness.
