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.
Fool
By a fool is signified he who is in falsities and evils from the love of self; consequently, from self-derived intelligence. To say “thou fool" indicates aversion to the good of charity.
