Wicked
Swedenborg several times associates the “wicked” with “malevolence,” defines “malevolence” as “destroying good, interior and exterior,” and says that the wicked do this by disowning the desire for good and understanding for good that come from the Lord and actively denying the Lord.
We might say, then, that wickedness is evil on the hunt, looking for all that is good and true specifically so it can attack and destroy it.

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.
