Psalms 78:4-7

We will not hide them from their children; we will tell to the coming generation the glorious deeds of the LORD, and his might, and the wonders that he has done. He established a decree in Jacob, and appointed a law in Israel, which he commanded our ancestors to teach to their children; that the next generation might know them, the children yet unborn, and rise up and tell them to their children, so that they should set their hope in God, and not forget the works of God, but keep his commandments
