Deuteronomy 6:20

"And it shall be when thy son asketh thee in time to come, saying, What is this? that thou shalt say unto him, By strength of hand the LORD brought us out from Egypt, from the house of bondage: in...: Heb. to morrow"

"And it shall come to pass, when your children shall say unto you, What mean ye by this service?"

"And thou shalt teach them diligently unto thy children, and shalt talk of them when thou sittest in thine house, and when thou walkest by the way, and when thou liest down, and when thou risest up."

"Train up a child in the way he should go: and when he is old, he will not depart from it. Train...: or, Catechise in...: Heb. in his way"
