Arcana Coelestia#4213
4213. 'And stayed the night in the mountain' means serenity. This is clear from the meaning of 'staying the night' as having peace, dealt with in 3170, and so as serenity. It was also the practice for those who entered into a covenant to spend the night together in one place, because staying the night in one place meant that no enmity existed any longer. The meaning in the internal sense is the existence of serenity and peace, for those who have been joined together as regards good and truth experience serenity and peace. The expression 'in the mountain' is therefore used here because 'a mountain' means good stemming from love and charity, 4210, it being this good that confers peace. What peace and serenity are, see 92, 93, 1726, 2780, 3170, 3696, 3780.

91. But unless man's state in which, from being spiritual, he is becoming celestial is known, one cannot possibly perceive what these expressions embody, for they are quite deep arcana. When he is spiritual, the external man is not yet willing to comply with and serve the internal man, and so there is conflict. But when he is becoming celestial, the external man starts to comply with and serve the internal. As a result conflict ceases, and tranquillity ensues; see 87. This tranquillity is meant by 'the rain' and by 'the mist', for it resembles a mist, with which his internal man waters and bathes the external. This serenity which is characteristic of Peace brings forth the things which are called 'the shrub of the field' and 'the plant of the field'. Specifically, these are the rational concepts and the facts that have a celestial-spiritual origin.
