Charles H. Spurgeon on Psalms 59:1

This Psalm has in its stern contents something no doubt strange to our ears. But never let us omit to distinguish from each other the times and diverse economies, and to place ourselves as far as possible, in sympathy with the experience of a heart which burned for nothing more than for the glorifying of God in this world. Everything that tended to obscure the theocratic relation of God to his people, called up in the soul of David the most vehement passion. The scornful oppression with which Saul and his venal satellites visited him, the man of God, could not but have, upon the eyes of all, the appearance as if Jehovah were no longer Lord in his own land, who inexorably adhered to his laws and rights. Treason, falsehood, and every kind of evil then prevailed unchecked. What wonder, that as formerly Moses in the wilderness was provoked against the stiff necked people, so also David, whom the awful holiness of God had already made to tremble, should feel his spirit stirred against the ungodly who surrounded him, and should say, with Job, "My bowels boiled within me." Frederick William Krummacher, D.D., in "David, the King of Israel, "1867.

O my God. There are two pleas which the psalmist makes use of; one was, that God was his God, Ps 59:1; the other was the power and strength of his enemies. It is a blessed thing to have the covenant to fly to in all times of straits and troubles; there is always an anchor hold of hope there. My God, is such a plea as infinitely over balances all other things. He has engaged himself to do his people good; and it is time for him to work when the enemy exalts himself. The church's enemies are never so near destruction as when they think they have nothing to do, but take and divide the spoil. We may plead God's promise and the enemies' power too; both are a ground of hope to a believer in Jesus. John Hill (1711-1746), in "Sermons on Several Occasions."
