Psalm 78 · a question people ask
Matthew quotes the words of 78:2 as "spoken through the prophet" (Matthew 13:35). The title names Asaph. Who spoke it?
Here is what each verse says. The psalm's title reads, "A contemplation by Asaph" (78:1), and the next verse is "I will open my mouth in a parable. I will utter dark sayings of old" (78:2). Matthew writes that Jesus spoke in parables "that it might be fulfilled which was spoken through the prophet" (Matthew 13:35), and quotes those words, worded a little differently in the WEB. Matthew doesn't give the prophet a name, and the psalm's title doesn't call Asaph a prophet. Psalm 50's chapter asks who Asaph is and sets out what 1 Chronicles says of an Asaph among the Levites; these notes don't repeat it, and they don't explain how Matthew's words and the title fit together.
The verses
“A contemplation by Asaph. Hear my teaching, my people. Turn your ears to the words of my mouth. I will open my mouth in a parable. I will utter dark sayings of old,”
“Jesus spoke all these things in parables to the multitudes; and without a parable, he didn’t speak to them, that it might be fulfilled which was spoken through the prophet, saying, “I will open my mouth in parables; I will utter things hidden from the foundation of the world.””
“A Psalm by Asaph. The Mighty One, God, the LORD, speaks, and calls the earth from sunrise to sunset.”
