Psalms 78:2-7

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, That they should place their confidence in God And not forget the works of God, But keep His commandments
