Bede, on 1Sam 9:25

“And they went down from the high place into the town, and he spoke with Saul upon the top of the house: and he prepared a bed for Saul on the top of the house, and he slept.”

“And he spoke with Saul in the upper room, etc. John spoke with the Lord in the light of His known divinity. For certainly the upper room (which takes its name from the fact that by its height it first receives the rays of the rising sun before the lower buildings) signifies the hearts of those who, suspended from earthly desires by divine fear, the Sun of Righteousness rises more familiarly. For when both, namely the Lord and John, had begun the commencement of their mission for which they were sent, and the grace of the new light had just begun to shine in the world, the same John confessed that Jesus Christ was the Son of God, while he himself was sent before Him, desiring Him with his whole intent of mind to rise to the works of the divine in the flesh, and to rest at the appropriate time from the duty of forerunning.”
