David continues to subdue his enemies, but then sins.

• Trust – In II Samuel, Joab was known for his vengeful actions. Here we see him in a different light.  In battle, he trusts God to do whatever seems good to the Lord (19:13).  Do you have that kind of trust in the Lord?
• Obedience – In chapter 21, David tells Joab to count the people – something David was not to do. Joab resists, finding the David’s sinful command to be abhorrent. Joab finally does grudgingly do it – an act of disobedience to God, but he still stands above David in this matter.  Do you find sin abhorrent to you?  Do you seek to obey God no matter who tells you otherwise?
