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.

Sent
'Being sent' means coming forth, (or going forth), in the internal sense, as in John 17:8. In similar manner, it is said of the holy of the spirit, that it was 'sent,' that is, it goes forth from the divine of the Lord, as in John 15:26, 16:5, 7.
So, too, the prophets were called 'the sent,' because the words which they spoke went forth from the holy of the spirit of the Lord.
'To be sent,' as in Genesis 37:13, signifies teaching.
