Gregory the Great, on 2Sam 7:3

“And Nathan said to the king: Go, do all that is in thy heart: because the Lord is with thee.”

“The spirit of prophecy doth not always illuminate the minds of the prophets; because, as it is written of the Holy Ghost that he breatheth where he will, so we are also to know that he doth breathe likewise for what cause, and when he pleaseth. And hereof it cometh, that when king David demanded of Nathan whether he might build a temple for the honour of God, the prophet Nathan gave his consent; and yet afterward utterly forbad it.”
