Prov 6:20 - 23 - My son, obey your father’s commands, and don’t neglect your mother’s instruction. Keep their words always in your heart. Tie them around your neck. When you walk, their counsel will lead you. When you sleep, they will protect you. When you wake up, they will advise you. For their command is a lamp and their instruction a light; their corrective discipline is the way to life.*
The words that a father speaks to his children in the privacy of home are not heard by the world, but, as in whispering-galleries, they are clearly heard at the end and by posterity.
