The King James Version of Job 2:2 reads:
And the LORD said unto Satan, From whence comest thou? And Satan answered the LORD, and said, From going to and fro in the earth, and from walking up and down in it. (KJV)
Translations in the King James family generally keep the "in", and it is also supported by, for example, Young's Literal Translation:
... And the Adversary answereth Jehovah and saith, 'From going to and fro in the land, and from walking up and down in it.' (YLT)
However, other translations have "on", for example:
... Satan answered the LORD, "From roaming throughout the earth, going back and forth on it." (NIV)
Does this verse suggest that Satan went below the surface of the Earth ("in") or only that walked about the surface ("on")?
