4 We will not hide them from their descendants; we will tell the next generation the praiseworthy deeds of the Lord, his power, and the wonders he has done.  5 He decreed statutes for Jacob and established the law in Israel, which he commanded our ancestors to teach their children, 6 so the next generation would know them, even the children yet to be born, and they in turn would tell their children.  7 Then they would put their trust in God and would not forget his deeds but would keep his commands.    Psalm 78:4-7 (NIV)
