Charles Spurgeon Commentary Matthew 13:32-35

"which indeed is less than all seeds; but when it is grown, it is greater than the herbs, and becometh a tree, so that the birds of the heaven come and lodge in the branches thereof. Another parable spake he unto them; The kingdom of heaven is like unto leaven, which a woman took, and hid in three measures of meal, till it was all leavened. All these things spake Jesus in parables unto the multitudes; and without a parable spake he nothing unto 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." — Matthew 13:32-35 (ASV)

But when it is grown, it is the greatest among herbs, and becometh a tree, so that the birds of the air come and lodge in the branches thereof. Another parable spake he unto them; The kingdom of heaven is like unto leaven, which a woman took, and hid in three measures of meal, till the whole was leavened. All these things spake Jesus unto the multitude in parables; and without a parable spake he not unto them: 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.

How thoroughly imbued our Lord was with the very spirit of Scripture. And he always acted as if the Scriptures were uppermost in his mind. They always seemed to be in their fullness before his soul.
