(8) Shut me up into the hand.--This is the exact phrase used by David (1Samuel 23:11-12) in consulting the Divine oracle by the ephod. But this does not prove the authorship, for it was evidently a common phrase. (See 1Samuel 24:18; 1Samuel 26:8; 2Kings 17:4.)

Large room.--Comp. Psalm 4:1; Psalm 18:19.

Verse 8. - And hast not shut me up into the hand of the enemy; i.e. "hast not delivered me up, without chance of escape, into the hands of my enemies" (comp. 1 Samuel 23:12). Thou hast set my feet in a large room. Given me, i.e., plenty of space and freedom for action; not confined me, nor cramped me, nor hindered me in any way (comp. Psalm 4:1; Psalm 18:36). Having cheered himself with the enumeration of these grounds of encouragement (vers. 5-8), the psalmist again returns to prayer.

31:1-8 Faith and prayer must go together, for the prayer of faith is the prevailing prayer. David gave up his soul in a special manner to God. And with the words, ver. 5, our Lord Jesus yielded up his last breath on the cross, and made his soul a free-will offering for sin, laying down his life as a ransom. But David is here as a man in distress and trouble. And his great care is about his soul, his spirit, his better part. Many think that while perplexed about their worldly affairs, and their cares multiply, they may be excused if they neglect their souls; but we are the more concerned to look to our souls, that, though the outward man perish, the inward man may suffer no damage. The redemption of the soul is so precious, that it must have ceased for ever, if Christ had not undertaken it. Having relied on God's mercy, he will be glad and rejoice in it. God looks upon our souls, when we are in trouble, to see whether they are humbled for sin, and made better by the affliction. Every believer will meet with such dangers and deliverances, until he is delivered from death, his last enemy.And hast not shut me up into the hand of the enemy,.... When in Keilah, in the wilderness of Ziph, and Maon, and encompassed about by Saul and his army, 1 Samuel 23:7; nor does the Lord suffer his people to be shut up under the power of sin and Satan, so that they cannot come forth in the exercise of grace, and the discharge of duty: but he brings their souls out of prison, that they may praise his name;

thou hast set my feet in a large room; at full liberty from his enemies; Saul and his army being called off from pursuing him, by tidings of an invasion by the Philistines, 1 Samuel 23:27; and this is the case of the saints when they are brought to Christ, to walk by faith at large on him; when grace is drawn forth into exercise, and spiritual knowledge is increased, and they are delivered from their enemies; or, however, can look upon them as conquered ones, and are sure of victory over them, and at last of an entire deliverance from them; see Psalm 4:1.
