Psalms 78:2-5

I will open my mouth in a parable; I will utter dark sayings of old, Which we have heard and known, And our fathers have told us. We will not hide them from their children, Telling to the generation to come the praises of the LORD, And His strength and His wonderful works that He has done. For He established a testimony in Jacob, And appointed a law in Israel, Which He commanded our fathers, That they should make them known to their children
