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.
Righteous
The word "righteous" has taken on a bit of negative shading in modern language. That may be because we hear it most often as part of the word "self-righteous," a rather scathing term for someone who thinks he is quite a good person -- almost certainly better than anyone around him -- and is in a position to judge others without being judged himself. The original word, however, is not negative at all: A righteous person is simply someone who does what is right. The spiritual meaning of "righteous" reflects that: people described as "righteous" act from a love of serving others, and that love is "righteousness." This is commonly described as "the good of charity," "charity" meaning a state of caring for others.
