Psalms 78:2-6

I will open my mouth in a parable [to instruct using examples]; I will utter dark and puzzling sayings of old [that contain important truth]— [Matt 13:34, 35] Which we have heard and known, And our fathers have told us. We will not hide them from their children, But [we will] tell to the generation to come the praiseworthy deeds of the LORD, And [tell of] His great might and power and the wonderful works that He has done. ¶For He established a testimony (a specific precept) in Jacob And appointed a law in Israel, Which He commanded our fathers That they should teach to their children [the great facts of God’s transactions with Israel], That the generation to come might know them, that the children still to be born May arise and recount them to their children
