Read Psalms 101:5-7  David was the king of Israel.  As the king, he needed to have people around him that could help him rule the country.  Our president is like that.  He needs good people to give him advice.  Advice means to tell someone what we think the best thing is to do.  But King David knew that there were wicked people who wanted to be around him just to have a good job or to wear fancy clothes and to be in an important place like the palace of the king.  So King David carefully watched his advisers.  Those who were trustworthy and honest, he listened to.  Those who lied and were proud and snooty, he got rid of.  The word slander is used in verse 5.  Slander means to talk about someone in a hurtful way.  We should be careful with what we say about someone.  The words that we use can hurt someone's feelings.  It may be better to think about saying something first, and then not say it than to say something hurtful and then to be sorry for saying it.  James 3 says that we should guard our tongue.  We need to be careful not to slander someone.  Then David talks about someone who works deceit in verse 7.  Deceit means to trick someone in a bad way.  David said that someone who used deceit would not stay near him.  King David wanted only honest and truthful advisers in his palace.  King David sounds like he was pretty smart.  How about you?  Do you have truthful friends or deceitful friends?  What kind of friends will help you to become a better person?  Let's take a lesson from King David.
