Charles H. Spurgeon on Psalms 144:11

Because of what the Lord had done, David returns to his pleading. He begs deliverance from him who is ever delivering him. Rid me, and deliver me from the hand of strange children. This is in measure the refrain of the song, and the burden of the prayer. He desired to be delivered from his open and foreign adversaries, who had broken compacts, and treated treaties as vain things. Whose mouth speaketh vanity, and their right hand is a right hand of falsehood. He would not strike hands with those who carried a lie in their right hand: he would be quit of such at once, if possible. Those who are surrounded by such serpents know not how to deal with them, and the only available method seems to be prayer to God for a riddance and deliverance. David in Ps 144:7, according to the original, had sought the help of both the Lord's hands, and well he might, for his deceitful enemies, with remarkable unanimity, were with one mouth and one hand seeking his destruction. Riddance from the wicked and the gracious presence of the Lord are sought with a special eye to the peace and prosperity which will follow thereupon. The sparing of David's life would mean the peace and happiness of a whole nation. We can scarcely judge how much of happiness may hang upon the Lord's favour to one man.
