v. 1. “Plead my cause”: he maintained it and the righteousness of it [1Sam.24:12]. Christ didn’t please his cause but committed Himself to Him who judges righteously; His people leave their cause with Him who is their Advocate; he pleads against wicked and ungodly men. He pleads against Satan, the accuser of the brethren, against our hearts that condemn us. “Fight against them”: The Lord does take the part of His people. v.2. “Shield and buckler”: defensive weapons – the Lord is the shield of salvation; He surrounds us with His favor as a shield. He keeps us by His power, safe from all enemies. “Stand up” – He delivers them out of the hands of the enemies. v.3. “The spear”: an offensive weapon – this is vengeance that God sometimes takes on enemies of His own. “Stop the way”: a wall of fire is imposed on those enemies. “I am thy salvation”: Christ is the salvation of His people. He is the author of our salvation and all that salvation means.
Psalm 35:1–3
