Charles H. Spurgeon on Psalms 60:4

Thou hast given a banner, etc. The psalmist compares the salvation which the Lord bestows upon his people to a highly excellent banner, which serves as a signal, to one lying prostrate in his misery, to rise up, with an allusion perhaps to Nu 21:8. "And the Lord said to Moses, Make thee a serpent, and set it upon a standard pole; and it happened that every one who was bitten, and looked at it, lived." At any rate, that passage in which the serpent is a symbol of the healing power of God, may serve to illustrate the passage before us. Compare heal its breaches. E. W. Hengstenberg.
