Proverbs 25
V. 19. Confidence in an unfaithful man, credulous reliance upon a false person, in time of trouble, when one is in need of a trustworthy friend, is like a broken tooth and a foot out of joint, worthless as they are, they provoke all the more by the infliction of pain.
V. 20. As he that taketh away a garment in cold weather, such a laying aside of warm clothing on a cold day being manifestly a senseless way of doing things, and as vinegar upon niter, the result being the destruction of the soda on account of the chemical reaction produced, so is he that singeth songs to an heavy heart, for songs of mirth in a house of mourning are contradictory and useless, Romans 12, 15.
V. 21. If thine enemy be hungry, give him bread to eat, readily sharing food with him, and if he be thirsty, give him water to drink; v. 22. for thou shalt heap coals of fire upon his head, kindness softening the heart as metals are melted by heaping glowing coals upon them, and the Lord shalt reward thee. Compare Matthew 5, 44; Romans 12, 20.
