LXX Psalm 77:2
1 Give heed, O my people, to my law: incline your ear to the words of my mouth. 2 I will open my mouth in parables: I will utter dark sayings which have been from the beginning. 3 All which we have heard and known, and our fathers have declared to us. 4 They were not hid from their children to a second generation; the fathers declaring the praises of the Lord, and his mighty acts, and his wonders which he wrought. 5 And he raised up a testimony in Jacob, and appointed a law in Israel, which he commanded our fathers, to make it known to their children:
Matthew 13:35
33 He told them another parable: “The kingdom of heaven is like yeast that a woman took and mixed with three measures of flour until all the dough had risen.” 34 Jesus spoke all these things in parables to the crowds; he did not speak to them without a parable. 35 This fulfilled what was spoken by the prophet: “I will open my mouth in parables, I will announce what has been hidden from the foundation of the world.” 36 Then he left the crowds and went into the house. And his disciples came to him saying, “Explain to us the parable of the darnel in the field.” 37 He answered, “The one who sowed the good seed is the Son of Man.
Notes and References
"... Breaking the feverish tension of the two previous chapters, with their condemnation and conflict, Matthew 13 provides at least temporary respite—a turn from polemics to didactics, from confrontation with the “brood of vipers” (12:34) “against” Jesus (12:30) to the veiled unveiling of parables that separate the crowds who, while blind, are not opposed to Jesus (13:2, 10, 13-15) and the disciples who, because they see, are “with” him (12:30). After the Parable of the Sower (13:1-9), Jesus answers the disciples’ question about why he speaks to the crowds in parables (13:10-17), explains the Sower (13:18-23), and tells three parables unified in theme (“spreading or growth”) and imagery (“farming, sowing, and its results”) (13:24-33). Before Jesus explains one of these (the Wheat and Weeds: 13:36-43), tells three more parables also unified in theme (“value or worth and discerning” it) and imagery (mercantile), and explains one of these (the Net of Fish: 13:50), the narrator divides the chapter, roughly in two, with a narrative summary (13:34) and an FC (13:35). The first part of the FC corresponds perfectly to Masoretic of Psalm 78:2 and LXX Psalm 77:2 ..."
