Charles H. Spurgeon on Psalms 19:11

"Moreover by them is thy servant warned." A certain Jew had formed a design to poison Luther, but was disappointed by a faithful friend, who sent Luther a portrait of the man, with a warning against him. By this, Luther knew the murderer and escaped his hands. Thus the word of God, O Christian, shows thee the face of those lusts which Satan employs to destroy thy comforts and poison thy soul. —G. S. Bowes, B.A., in "Illustrative Gatherings for Preachers and Teachers."
