Satan as the accuser

Job 1 vs. 7                                                                                             

And the LORD said unto Satan, Whence comest thou? Then Satan answered the LORD, and said, From going to and fro in the earth, and from walking up and down in it.

1. Satan is a wanderer. He walks about causing troubles.
2. Satan is  a busy body. He intervenes in matters uninvited
3. Satan is a trouble maker. He delights in causing troubles for people.
