At the beginning of the weekday Maariv prayer service, we say a verse from Psalms 78:38.
The Artscroll translation reads:
"He the Merciful One is forgiving of iniquity and does not destroy frequently withdrawing His anger not arousing His entire rage"
We learn from here that G-d does not destroy frequently, but I want to know:
how often DOES G-d destroy?
Who/what is He destroying?
What does G-d's infrequent destroying have to do with the Maariv prayer serivce?
