Psalm78: I will cause riddles of long ago to bubble forth

2 In a proverbial saying I will open my mouth; I will cause riddles of long ago to bubble forth. (Psalm78)

34 All these things Jesus spoke to the crowds by illustrations. Indeed, without an illustration he would not speak to them;
35 that there might be fulfilled what was spoken through the prophet who said: I will open my mouth with illustrations, I will publish things hidden since the founding. (Matthew 13).

1 Do give ear, Oh my people, to my law; Incline your ear to the sayings of my mouth.
2 In a proverbial saying/parable I will open my mouth; I will cause riddles of long ago to bubble forth [their meanings through more riddles the meanings of which I reveal to my disciples. So Jesus reveals how to interpret old riddles by giving new riddles and their interpretations to his disciples. This is what we are doing with new testament quotes of old testament scriptures],
3 Which we have heard and know, And which our own fathers have related to us;
4 Which we do not hide from their sons, Relating [them] even to the generation to come, The praises of Jehovah and his strength And his wonderful things that he has done.
5 And he proceeded to raise up a reminder in Jacob, And a law he set in Israel, Things that he commanded our forefathers, To make them known to their sons;
6 In order that the generation to come, the sons that were to be born, might know [them], That they might rise up and relate [them] to their sons,
7 And that they might set their confidence in God himself And not forget the practices of God but observe his own commandments.
8 And they should not become like their forefathers, A generation stubborn and rebellious, A generation who had not prepared their heart And whose spirit was not trustworthy with God (Psalm 78).
