A man who has friends must himself be friendly, but there is a friend who sticks closer than a brother. 

           proverbs 18:24

A friend loves at all times, And a brother is born for adversity.        proverbs    17:17

Do not forsake your own friend or your father's friend, nor go to your brother's house in the day of your calamity; Better is a neighbor nearby than a brother far away.          proverbs 27:10

Even my own familiar friend in whom I trusted, who ate my bread, has lifted his heel against me.
