Don't breeze through this chapter. It is vital in understanding the story of David.
Community matters. Even for a king.
Here we read of the mighty men that fought behind and beside David in some of his most dangerous and challenging events of his life. These men dealt with death and life, victory and defeat together. They lived in the city gates and hid in caves. Through it all, they did it together. Life is meant to be lived in community with a few people that are willing to do the bad and the good with you.
