Gill's Exposition of the Entire BibleThou 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.

Matthew Henry's Concise Commentary119:113-120 Here is a dread of the risings of sin, and the first beginnings of it. The more we love the law of God, the more watchful we shall be, lest vain thoughts draw us from what we love. Would we make progress in keeping God's commands, we must be separate from evil-doers. The believer could not live without the grace of God; but, supported by his hand, his spiritual life shall be maintained. Our holy security is grounded on Divine supports. All departure from God's statutes is error, and will prove fatal. Their cunning is falsehood. There is a day coming which will put the wicked into everlasting fire, the fit place for the dross. See what comes of sin Surely we who fall so low in devout affections, should fear, lest a promise being left us of entering into heavenly rest, any of us should be found to come short of it, Heb 4:1.
Matthew Henry's Whole Bible CommentaryVerse 114 Here is, 1. God's care of David to protect and defend him, which he comforted himself with when his enemies were very malicious against him: Thou art my hiding-place and my shield. David, when Saul pursued him, often betook himself to close places for shelter; in war he guarded himself with his shield. Now God was both these to him, a hiding-place to preserve him from danger and a shield to preserve him in danger, his life from death and his soul from sin. Good people are safe under God's protection. He is their strength and their shield, their help and their shield, their sun and their shield, their shield and their great reward, and here their hiding-place and their shield. They may by faith retire to him, and repose in him as their hiding-place, where they are kept in secret. They may by faith oppose his power to all the might and malice of their enemies, as their shield to quench every fiery dart. 2. David's confidence in God. He is safe, and therefore he is easy, under the divine protection: "I hope in thy word, which has acquainted me with thee and assured me of thy kindness to me." Those who depend on God's promise shall have the benefit of his power and be taken under his special protection. |
