"Observe, O my son, the commandment of your father, and do not forsake the law of your mother. Tie them upon your heart constantly; bind them upon your throat. When you walk about, it will lead you; when you lie down, it will stand guard over you; and when you have waked up, it itself will make you its concern. For the commandment is a lamp, and a light the law is, and the reproofs of discipline are the way of life." -- Proverbs 6: 20-23 (NWT), emphasis added
The similarities between these passages are too great to ignore. This is particularly true when one considers that the Proverbs passage is one of six chapters whose theme is wisdom, which for most people is synonymous with truth.
