Charles H. Spurgeon on Psalms 71:10

For mine enemies speak against me. Dogs howl over a dying lion. When David's arm was able to chastise his foes, they were yet impudent enough to slander him, and he fears that now they will take fresh license in the hour of his weakness. The text most properly means that his enemies had said that God would forsake him; and, therefore, he is the more earnest that the Lord's faithful dealings may give them the lie. And they that lay wait for my soul take counsel together. The psalmist had enemies, and these were most malicious; seeking his utter destruction, they were very persevering, and staid long upon the watch; to this they added cunning, for they lay in ambush to surprise him, and take him at a disadvantage; and all this they did with the utmost unanimity and deliberation, neither spoiling their design by want of prudence, nor marring its accomplishment by a lack of unity. The Lord our God is our only and all sufficient resort from every form of persecution.
