Arcana Coelestia#10301
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.
Jehovah
The Lord, in the simplest terms, is love itself expressed as wisdom itself. In philosophic terms, love is the Lord's substance and wisdom is His form. Of course, we feel the Lord's love and hear His wisdom in many different ways, depending on our state in life and how receptive we are. That's why the Lord has so many different names in the Bible, and is referred to in so many different ways.
