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. And it shall be our righteousness, if we observe to do all these commandments before the LORD our God, as he hath commanded us. And Moses wrote this law, and delivered it unto the priests the sons of Levi, which bare the ark of the covenant of the LORD, and unto all the elders of Israel. Parents are given the command to teach their children about God, who He is, what His commandments are for every part of their life and to pass it down from generation to Generation for their prosperity and health. The Word train means to initiate or discipline, to show, to be an example.
Parents are to lead their children in the right path.
God gave charge to the man of God to bring parents and their children into the house of God to hear Gods Word and to live for him. God wants children to know knowledge and Doctrine. Jesus tells us of the end of the world and how he will come again without warning. He also tells us how to be ready according to His Word. Notice judgment will fall on all.
