Prov 6:20-23
20 My son, keep your father's command, and do not forsake the law of your mother.
21 Bind them continually upon your heart; Tie them around your neck.
22 When you roam, they will lead you; when you sleep, they will keep you; and when you awake, they will speak with you.
23 For the commandment is a lamp, and the law a light; reproofs of instruction are the way of life, (NKJ)
