Charles H. Spurgeon on Psalms 35:1

"Plead my cause, O Lord, with them that strive with me." Plead against those who plead against me; strive with my strivers; contend with my contenders. If they urge their suit in the law-court, Lord, meet them there, and beat them at their own weapons. Every saint of God shall have this privilege: the accuser of the brethren shall be met by the Advocate of the saints. "Fight against them that fight against me." If my adversaries try force as well as fraud, be a match for them; oppose thy strength to their strength. Jesus does this for all his beloved —for them he is both intercessor and champion; whatever aid they need they shall receive from him, and in whatever manner they are assaulted they shall be effectually defended. Let us not fail to leave our case into the Lord's hand. Vain is the help of man, but ever effectual is the interposition of heaven. What is here asked for as a boon, may be regarded as a promise, to all the saints; in judgment they shall have a divine advocate, in warfare a divine protection.
