Here is, 1. David in danger of losing his life. There is but a step between him and death, for the wicked have laid a snare for him; Saul did so many a time, because he hated him for his piety. Wherever he was he found some design or other laid against him to take away his life, for it was that they aimed at. What they could not effect by open force they hoped to compass by treachery, which made him say, My soul is continually in my hand. It was so with him, not only as a man (so it is true of us all; wherever we are we lie exposed to the strokes of death; what we carry in our hands is easily snatched away from us by violence, or if sandy, as our life is, it easily of itself slips through our fingers), but as a man of war, a soldier, who often jeoparded his life in the high places of the field, and especially as a man after God's own heart, and, as such, hated and persecuted, and always delivered to death (Co2 4:11), killed all the day long. 2. David in no danger of losing his religion, notwithstanding this, thus in jeopardy every hour and yet constant to God and his duty. None of these things move him; for, (1.) He does not forget the law, and therefore he is likely to persevere. In the multitude of his cares for his own safety he finds room in his head and heart for the word of God, and has that in his mind as fresh as ever; and where that dwells richly it will be a well of living water. (2.) He has not yet erred from God's precepts, and therefore it is to be hoped he will not. He had stood many a shock and kept his ground, and surely that grace which had helped him hitherto would not fail him, but would still prevent his wanderings.

Thou art my hiding place,.... From temporal calamities. The perfections of God are chambers of retreat and safety to his people, where they may hide themselves and be safe, till such calamities are over, Isa 26:20. And from spiritual evils; from avenging justice, from divine wrath, from the rage of Satan, and the fury of men, Isa 32:2; and from eternal death, and being hurt by it; the spiritual and eternal life of saints being hid with Christ in God, Col 3:3; see Psa 32:7;

and my shield; to protect from all dangers, and preserve from every enemy: such are the love and grace, the power and strength, the truth and faithfulness of God; which are the saints' shield and buckler, Psa 5:12; such also the person, blood, righteousness, and salvation of Christ, who is a sun and shield; the shield of faith, or which faith holds up and defends the soul against the attacks of a powerful enemy, Psa 84:11;

I hope in thy Word; in Christ the Word, for acceptance and justification, for peace, pardon, and eternal salvation; all which are in him: in the word of promise, for all supplies of grace, strength, light, life, and comfort here, and for glory hereafter, contained therein; see Psa 119:74.
