Back to David in chapter 29, we find him in the uncomfortable situation of marching to war with the Philistines against his own country. Some of the leaders of the Philistines aren't happy and insist that David go away.
The SAB notes that the word in the Hebrew used of David is "Satan", but I'm not sure what's noteworthy about this. I think most people who know anything of Hebrew (well, I guess that's not too many) know that "Satan" is a Hebrew word meaning "adversary". Also, they make mention of the song about David being a great warrior. It is decided that David should leave, and so he does.
