3022. Verses 3-4 And I will make you swear by Jehovah, the God of heaven and the God of the earth, that you do not take a wife for my son from the daughters of the Canaanites in whose midst I am dwelling, but that you go to my land and to the place of my nativity; and you shall take a wife for my son Isaac.

'And I will make you swear by Jehovah, the God of heaven and the God of the earth' means an utterly sacred binding to the Divine which existed in highest things and in the things derived from these. 'That you do not take a wife for my son from the daughters of the Canaanites' means that the Divine Rational should not be joined to any affection incompatible with truth. 'In whose midst I am dwelling' means incompatible things in the maternal human that surround. 'But go to my land and to the place of my nativity' means to the Divine celestial and spiritual things which the Lord acquired to Himself. 'And you shall take a wife for my son Isaac' means that from this came the affection for truth which was to be joined to the affection for good belonging to the Rational.

2996. Though in this world a very deep arcanum, nothing is better known in the next life, known even to every spirit, than the truth that all things in the human body have a correspondence with things in heaven. So true is this that not even the smallest part in the human body fails to have something spiritual and celestial, or what amounts to the same, the heavenly communities, corresponding to it. For heavenly communities exist according to all the genera and species of spiritual and celestial things; indeed they exist in such order that all of them together represent one human being. They do so in every single detail of the human being, both interior and exterior. This is why heaven considered as a whole is also called the Grand Man, and why so many times already one community has been spoken of as belonging to this part of the body, another community to that, and so on. The reason why heaven is described in this way is that the Lord is the only Man and heaven represents Him. Also it is Divine Good and Truth received from Him that constitute heaven, and therefore as angels are in heaven they' are said to be in the Lord. Those in hell however are outside of that Grand Man. These correspond to filth and also to things full of disease.
