8108. 'And by night in a pillar of fire to give them light' means that when there was a state of dimness, this was moderated by enlightenment from good. This is clear from the meaning of 'night' as a state of obscurity or dimness, dealt with in 1712, 6000; from the meaning of 'fire' as the good of love, dealt with in 934, 4906, 5215, 6314, 6832, 6834, 6849, 7324, 7852; and from the meaning of 'giving light' as enlightenment. The reason why Jehovah or the Lord appeared or led the way in a pillar of cloud during the daytime and in a pillar of fire by night was that the state of heaven was represented thereby. In heaven variations and changes of state occur unceasingly; for angels are being perfected constantly, and without unceasing changes of states this perfecting could not possibly take place. In general those variations and changes are like the cyclic changes in the world - like the round of yearly seasons, which are spring, summer, autumn, winter, and spring again, and like the round of times of day, which are morning, midday, evening, night, and morning again. Morning and midday in heaven occurs when the understanding is being enlightened by the Lord; but in this state the light is moderated by a dimming of truth, as if by a cloud. And evening and night there occur when the understanding grows dim; but the Lord moderates that dimness by means of the good of love, as if by means of a fire giving light. These provisions by the Lord are what were represented by the pillar of cloud during the daytime, and the pillar of fire by night, present with the children of Israel in the wilderness.

4906. 'Bring her out, and let her be burnt' means that it - that is to say, the internal aspect of the Church which Tamar represented - should be exterminated. This is clear from the meaning of 'bringing her out, and burning her' as exterminating, 'bringing out' having reference to the truth and 'burning' to the good which were to be exterminated. The use of 'burning' in reference to the extermination of good is clear from many places in the Word. The reason for the usage is that in the spiritual sense 'fire' and 'flame' mean good, 934, and the heat radiated from them the affection for good, while 'fire' and 'flame' in the contrary sense mean evil, and the heat radiated from these the affection for evil, 1297, 1861, 2446. Also, in actual fact good is spiritual fire from which spiritual heat which is life-giving is radiated; and evil too is a fire, but from this a heat which is a consuming one is radiated. Anyone who turns his attention to this matter and reflects on it can plainly see that the good of love is spiritual fire, and that the affection for that good is spiritual heat if he reflects on the question where do man's vital fire and heat come from, he will discover that love is the source of it; for as soon as love departs a person begins to grow cold, but as love increases in him he becomes warmer. Unless man's vital fire and heat came from that source he could not possibly have life at all. But this life-bringing fire or spiritual heat becomes among the evil a destroying and consuming fire, for in their case it is converted into this kind of fire. Among living creatures which do not possess reason spiritual heat likewise flows in and brings life, but life which is varied, depending on the ways in which their organic forms, and therefore their knowledge and innate affections receive that life, as with bees and all other creatures.
