8909. Verse 17 You shall not covet your neighbour's house; you shall not covet your neighbour's wife, nor his male slave nor his female slave, nor his ox nor his ass, nor anything that is your neighbour's means that one must be on one's guard against self-love and love of the world, and so one must take care to prevent the evils contained in the preceding commandments from becoming present in the will and consequently going out of it.

10301. 'Pure' means devoid of evil. This is clear from the meaning of 'pure' as devoid of evil. Because all evil is impure, and all good is pure, the expression 'being purified' from sins and from iniquities is used. And it has regard to the heart, that is, the will; for the will is meant in the Word by 'the heart', 2930, 7542, 8910, 9300, 9495, since love is meant by it, 3883-3896, 9050.
Arcana Coelestia #1000
1000. 'Soul' means life. This becomes clear from the meaning of 'soul' in many places in the Word. In general 'soul' in the Word means life in its entirety, the internal life, or that of the internal man, as well as the external, or that of the external man. And because it means life in its entirety it means the nature of the life present in the one to whom 'soul' has reference. In this case it has reference to the life of someone who is regenerate, which is separate from the merely human will. For as stated already, the new life which a regenerate spiritual person receives from the Lord is completely separate from the person s own will or proprium, that is, from the life that is his own, which though called such is not really life but death because it is the life belonging to hell. This is why 'flesh with its soul which they were not to eat' means flesh together with its soul, that is, they were not to mix together this new life which is the Lord's with the evil or putrid life that is man's, that is, with his own will or proprium.
