Micah 7

"Do not trust in a friend;
Do not put your confidence in a companion;
Guard the doors of your mouth
From her who lies in your bosom.
6 For son dishonors father,
Daughter rises against her mother,
Daughter-in-law against her mother-in-law;
A man’s enemies are the men of his own household.
7 Therefore I will look to the Lord;
I will wait for the God of my salvation;
My God will hear me." vv.5-7

Read chapter 7.
Who can one trust if not his friends or family?  Those who are supposed to insure justice in Israel are corrupt and take bribes (v.3).  They are such traitors that a man cannot even trust his own family.  Perhaps Micah experienced this?  This is all happening before the captivity showing how corrupt Israel had become.  Today this is common in many homes of the family being their own enemies yet in other homes their families are their best friends.  The ways of the world cause man to be selfish and it in turn causes mistrust, deceitfulness, sin in relationships.  How can you fight against that in your relationships with friends and family?  No matter what, when all fails God remains.
Who left to look to but YAHWEH!
