Charles H. Spurgeon on Psalms 109:1

Hold not thy peace. Mine enemies speak, be thou pleased to speak too. Break thy solemn silence, and silence those who slander me. It is the cry of a man whose confidence in God is deep, and whose communion with him is very close and bold. Note, that he only asks the Lord to speak: a word from God is all a believer needs. O God of my praise. Thou whom my whole soul praises, be pleased to protect my honour and guard my praise. "My heart is fixed", said he in the former psalm, "I will sing and give praise", and now he appeals to the God whom he had praised. If we take care of God's honour he will take care of ours. We may look to him as the guardian of our character if we truly seek his glory. If we live to God's praise, he will in the long run give us praise among men.
