1 Samuel 3:15

Samuel slept until morning, etc. The Lord remained in secret rest with the Father, with whom he ceaselessly arranged and governed all things invisibly, waiting for when, with the night of vices dispelled by the host of virtues, the lights of evangelical truth would reveal …

21. For he sleeps until morning who rests in the conduct of a good work begun until the splendor of the coming Redeemer appears. He sleeps until morning who throughout the whole night of the present life waits through the purpose of justice begun, so that the brightness of the promised Redeemer may shine forth for him unto the joy of a merited reward.

22. What is it that Samuel's sleep is described so attentively through sacred Scripture? And since he is said to have repeated his sleep four times already, anyone who does not believe this was spoken spiritually by the Spirit of God is greatly foolish. For even if he is rightly understood to have slept so many times according to the truth of history, it is written for this purpose: that from the truth of the letter, meanings of allegory may be brought forth. What then does this fifth sleep of Samuel signify? But since we referred the first sleep to the pursuit of truth, the second to the testing of true work, the third to the exploration of true joy, the fourth to the full enjoyment of perfection found, proven, and known, the fifth kind of sleep is referred to the effort of arranging one's speech. Samuel therefore slept a fifth time, because the order of preachers, even though through the counsel of the heart it learned the truth, through the will of the mind chose good things, through the affection of virtue received true joy, and through the certainty of beatitude found and known rested in the security of sublime virtues, nevertheless could not preach to those under its care what it had come to know within itself without the great ordering of counsel. For very often a teacher both possesses within himself what he should preach, and yet cannot preach what he possesses as he ought, because even if he has already learned by the Lord's revelation what to say, he does not know the manner in which it should be brought forth to the people. Samuel therefore slept again, because the order of preachers disposed within itself with great intent of quiet lest by preaching it scatter uselessly the seed of God's word that it had gathered by profitable contemplation.

Doors - Altho' the tabernacle, whilst it was to be removed from place to place in the wilderness, had no doors, but consisted only of curtains, and had hangings before the entrance, instead of doors; yet when it was settled in one place, as now it was in Shiloh, it was enclosed within some solid building, which had doors and posts, and other parts belonging to it.

Our secret communion with God is not to be proclaimed upon the house-tops. (3.) He feared to show Eli the vision. If he was afraid Eli would be angry with him and chide him, then we have cause to suspect that Eli used to be as severe with this towardly child as he was indulgent to his own wicked sons, and this will bear hard upon him.
