Slay them not, lest my people forget. It argues great faith on David's part, that even while his house was surrounded by his enemies he is yet so fully sure of their overthrow, and so completely realises it in his own mind, that he puts in a detailed petition that they may not be too soon or too fully exterminated. God's victory over the craft and cruelty of the wicked is so easy and so glorious that it seems a pity to end the conflict too soon. To sweep away the plotters all at once were to end the great drama of retribution too abruptly. Nay, let the righteous be buffeted a little longer, and let the boasting oppressor puff and brag through his little hour, it will help to keep Israel in mind of the Lord's justice, and make the brave party who side with God's champion accustomed to divine interpositions. It were a pity for good men to be without detractors, seeing that virtue shines the brighter for the foil of slander. Enemies help to keep the Lord's servants awake. A lively, vexatious devil is less to be dreaded than a sleepy, forgetful spirit which is given to slumber. Scatter them by thy power. Blow them to and fro, like chaff in the wind. Let the enemy live as a vagabond race. Make Cains of them. Let them be living monuments of divine power, advertisements of heaven's truth. To the fullest extent let divine justice be illustrated in them. And bring them down. Like rotten fruit from a tree. From the seats of power which they disgrace, and the positions of influence which they pollute, let them be hurled into humiliation. This was a righteous wish, and if it be untempered by the gentleness of Jesus, we must remember that it is a soldier's prayer, and the wish of one who was smarting under injustice and malice of no ordinary kind. O Lord, our shield. David felt himself to be the representative of the religious party in Israel, and therefore he says, our shield, speaking in the name of all those who make Jehovah their defence. We are in good company when we hide beneath the buckler of the Eternal; meanwhile he who is the shield of his people is the scatterer of their enemies.
