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.
Arcana Coelestia #1819
1819. 'He said, O Lord Jehovih' means a conversing, so to speak, of the Interior Man with the Internal Man. This is clear from what was stated in the previous verse at the words 'Jehovah said to him', and also from what was stated in verse 2 of this chapter about the Lord Jehovih, as meaning a conversing of the Interior Man with the Internal Man, or Jehovah, especially when He was undergoing temptation.
