Charles H. Spurgeon on Psalms 119:23

But thy servant did meditate in thy statutes. Perceive here the armour by which David fights against his enemy. Arma justi quibus omnes adversariorum repellit impetus, his weapons are the word and player. He renders not injury for injury, reproach for reproach. It is dangerous to fight against Satan or his instruments with their own weapons; for so they shall easily overcome us. Let us fight with the armour of God the exercises of the word and prayer: for a man may peaceably rest in his secret chamber, and in these two see the miserable end of all those who are enemies to God's children for God's sake. William Cowper.
