Charles H. Spurgeon on Psalms 119:114

Shield. The excellency and properties of a shield lie in these things: 1. In the largeness and breadth of it, in that it hides and covers the person that weareth it from all darts that are flung at him, so as they cannot reach him: Thou, Lord, wilt bless the righteous; with favour wilt thou compass him as with a shield (Psalms 5:12). 2. The excellence of a shield lies in that it is hard and impenetrable. So this answers to the invincible power of God's providence, by which he can break the assaults of all enemies; and such a shield is God.to his people: "My shield, and he in whom I trust" (Psalms 144:2). 3. Shall I add one thing more? Stones and darts flung upon a hard shield are beaten back upon him that flings them; so God beats back the evil upon his enemies and the enemies of his people: "Bring them down, O Lord, our shield" (Psalms 59:11). Thomas Manton.
