Matthew Poole and continuators on Matthew 13:35

35 That it might be fulfilled which was spoken by the Prophet, saying, I will open my mouth in parables, I will utter things which have been kept secret from the foundation of the world.

Christ spake all the afore mentioned things to the Multitude, and also to his Disciples in Parables, dark sayings, covering Divine, and Spiritual Truths, with fit, and proper Similitudes, and at this time he delivered himself wholly in this manner to them, tho at other times he spake more plainly. He gave us the reason before, and by this way of speaking, also he made his own Disciples more diligent to attend to what they heard, and more inqu[illegible: 2 letters]tive after the true sense and meaning of it. And thus saith the Evangeli[illegible: 1 letter]t, that which was spoken by the Pro[illegible: 1 letter]het, Psa[illegible: 1 letter]. 78.2. was also fulfilled in Christ, not that the Psalmist, whether David or Asaph, did there Prophecy concerning Christ, for plainly the Psalmist intended to relate the History of Gods dealing with the Iews, and their behaviour toward him. Nor was it fulfilled, as the Type in the Antitype, but as a thing of the same Nature was done; the Prophet delivered himself in dark Sayings, so did Chri[illegible: 1 letter]t, but instead of I will utter dark sayings of old, the Evangelist hath, which have been kept secret, from the Foundation of the World, he means the great, and Mysterious things of the Gospel, hid from Ages and Generations, Rom. 16.25. 1 Cor. 2.7. Colos. 1.26. where it is called the Revelation of the Mystery, which was kept secret since the World began, Eph▪ 3.9. As the Psalmist opened his Mouth in Grave Discourses, tending to the good of the People, to whom he spake: So Christ taught the People, by revealing the Mysteries of the Gospel, hid in God from the beginning of the World, as Paul speaks to the Ephesians.
