Thou art my hiding place and my shield. The meaning is, that the prophet, persuaded that the only way in which he could be safe, was by lying hid under the wings of God, confided in his promises, and, therefore, feared nothing. And, assuredly, the first point is, that the faithful should hold it as a settled principle, that amidst the many dangers to which they are exposed, the preservation of their life is entirely owing to the protection of God; in order that they may be excited to flee to him, and leaning upon his word, may confidently wait for the deliverance which he has promised. This confidence, That God is our refuge and our shield, is, no doubt, derived from the word; but we must remember that there is here a mutual relation -- that, when we have learned from the word of God that we have in him a safe hiding-place, this truth is to be cherished and confirmed in our hearts, under a consciousness of our absolute need of the divine protection. Besides, although his power ought abundantly to suffice in inspiring us with the hope of salvation, yet we should always set the word before us, that our faith may not fail when his aid is slow in coming.

Thou art my hiding place - See the notes at Psalm 32:7, where the same expression occurs.
And my shield - See Psalm 5:12, note; Psalm 84:11, note.
I hope in thy word - See Psalm 119:74, Psalm 119:81.

Mv hiding place - My asylum.
And my shield - There is a time in which I may be called to suffer in secret; then thou hidest me. There may be a time in which thou callest me to fight; then thou art my Shield and Protector.

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, Isaiah 26:20. And from spiritual evils; from avenging justice, from divine wrath, from the rage of Satan, and the fury of men, Isaiah 32:2; and from eternal death, and being hurt by it; the spiritual and eternal life of saints being hid with Christ in God, Colossians 3:3; see Psalm 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, Psalm 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, Psalm 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 Psalm 119:74.
