Verse 13. Arise, O Lord. The more furious the attack, the more fervent the Psalmist's prayer. His eye rests singly upon the Almighty, and he feels that God has but to rise from the seat of his patience, and the work will be performed at once. Let the lion spring upon us, if Jehovah steps between we need no better defence. When God meets our foe face to face in battle, the conflict will soon be over.
Disappoint him. Be beforehand with him, outwit and outrun him. Appoint it otherwise than he has appointed, and so disappoint him.
Cast him down. Prostrate him. Make him sink upon his knees. Make him bow as the conquered bows before the conqueror. What a glorious sight will it be to behold Satan prostrate beneath the foot of our glorious Lord! Haste, glorious day!
Deliver my soul from the wicked, which is thy sword. He recognizes the most profane and oppressive as being under the providential rule of the King of kings, and used as a sword in the divine hand. What can a sword do unless it be wielded by a hand? No more could the wicked annoy us, unless the Lord permitted them so to do. Most translators are, however, agreed that this is not the correct reading, but that it should be as Calvin puts it, "Deliver my soul from the ungodly man by thy sword." Thus David contrasts the sword of the Lord with human aids and reliefs, and rests assured that he is safe enough under the patronage of heaven.
EXPLANATORY NOTES AND QUAINT SAYINGS
Verse 13. The wicked, which is thy sword. The devil and his instruments both are God's instruments, therefore "the wicked" are called his "sword," his "axe" (Ps 17:13 Isaiah 10:15 ); now let God alone to wield the one, and handle the other. He is but a bungler that hurts and hackles his own legs with his own axe; which God should do if his children should be the worse for Satan's temptations. Let the devil choose his way, God is a match for him at every weapon. If he will try it by force of arms, and assaults the saints by persecution, as the "Lord of hosts" he will oppose him. If by policy and subtlety, he is ready there also. The devil and his whole council are but fools to God; nay, their wisdom foolishness. William Gurnall.
Verse 13-14. Thy sword... thy hand. Thou canst as easily command and manage them, as a man may wield his sword, or move his hand. Wilt thou suffer thine own sword, thine own hand, to destroy thine own servant? J. Howe
