The number "two" has two different meanings in the Bible. In most cases "two" indicates a joining together or unification. This is easy to see if we consider the conflicts we tend to have between our "hearts" and our "heads" -- between what we want and what we know. Our "hearts" tell us that we want pie with ice cream for dinner; our "heads" tell us we should have grilled chicken and salad. If we can bring those two together and actually want what's good for us, we'll be pretty happy. We're built that way -- with our emotions balanced against our intellect -- because the Lord is built that way. His essence is love itself, or Divine Love, the source of all caring, emotion and energy. It is expressed as Divine Wisdom, which gives form to that love and puts it to work, and is the source of all knowledge and reasoning. In His case the two aspects are always in conjunction, always in harmony. It's easy also to see how that duality is reflected throughout creation: plants and animals, food and drink, silver and gold. Most importantly, it's reflected in the two genders, with women representing love and men representing wisdom. That's the underlying reason why conjunction in marriage is such a holy thing. So when "two" is used in the Bible to indicate some sort of pairing or unity, it means a joining together. In rare cases, however, "two" is used more purely as a number. In these cases it stands for a profane or unholy state that comes before a holy one. This is because "three" represents a state of holiness and completion (Jesus, for instance, rose from the tomb on the third day), and "two" represents the state just before it.

9216. 'In which he may sleep' means resting on them. This is clear from the meaning of 'sleeping' as resting, in this instance on the external and sensory level, meant by 'clothing', 9212; for it says that it is clothing 'in which he may sleep'. How the explanation that more internal things find rest on the sensory level should be understood must be stated. The sensory level is the last and lowest of a person's life, as has been shown above. What is lowest contains all the more internal levels and is general to them all; for they terminate in it and accordingly rest on it. It is like the skin, for example, which is the outermost covering of the body. The body and all things in it terminate in the skin, because it contains them and they accordingly rest on the skin. In a similar way it is like the peritoneum within the body. Because it contains the abdominal organs, these rest on it and are also linked to it all round. Or equally it is like the pleura's relationship to the organs in the chest.

[2] A similar situation exists with all the things that compose a person's actual life, with those for instance that are connected with his understanding and those that are connected with his will. These too follow one another in order from more internal things to relatively external ones. The relatively external ones are factual knowledge together with its delights, while the outermost things are those of the senses, which are in contact with the world through sight, hearing, taste, smell, and touch. The more internal things rest on them since they terminate in them. These are the matters that are meant in the spiritual sense by 'the covering' or 'the clothing in which he may sleep'. The reason why things on the level of the senses are meant by 'the clothing' or 'the covering' lies in correspondences; for as stated above in 9212, spirits and angels appear dressed in garments in keeping with their truths of faith. Those governed by truths springing from good appear in shining ones, as for instance those at the Lord's tomb did, Luke 24:4; Matthew 28:3, and also in ones of fine, white linen, as for instance those referred to in Revelation 19:14 did; and others appear in garments of various colours.

[3] Furthermore it should be realized that all things without exception proceed in successive stages from their first or inmost level to their terminations on the last and lowest and rest on them. Each thing at a prior or more internal stage in order has its own connection with terminations on the lowest level. Therefore if things on the lowest level are dispelled those on interior levels are also scattered. This also explains why there are three heavens. The inmost or third heaven flows into the middle or second heaven; the middle or second heaven flows into the first or lowest heaven, which in turn flows into and resides with mankind. Consequently the human race constitutes the lowest level of order; in it heaven terminates and on it heaven rests. This being so, the Lord in His Divine [Love and Care] always provides for the presence among the human race of a Church in which truth revealed by God exists; such truth on our planet is the Word. By means of this a continuous link exists between the human race and the heavens. This is why every detail of the Word has within it an internal sense which exists for heaven's benefit and whose nature is such that it joins angels' minds to those of people on earth in so firm a bond that they act as one. All this goes to show yet again the nature of a situation in which interior things rest on those at the lowest level.
