In a dream, in a vision, or, in a vision of the night This he mentions as one usual way of God's revealing his mind and will to men in those days, before God's word was committed to writing; (Genesis 20:6; Genesis 41:1; Genesis 41:28;) when deep sleep falleth upon men When men's outward senses are bound up, and their minds are free from all distracting cares and business of the world, and wholly at leisure to receive divine impressions; in slumberings upon the bed This is added because, in this case, man is like one that slumbereth, or is between sleeping and waking, or uncertain in which state he is, as Paul, when he was in his ecstasy, could not tell whether he was in the body or out of the body.
