'Friend' in the Bible

I paced about as for my friend or my brother, and fell down mourning as one weeps for one's mother.

As for my best friend, the one in whom I trusted, the one who ate my bread, even he has insulted me!

but it is you a man whom I treated as my equal my personal confidant, my close friend!

You caused my friend and neighbor to shun me; and my acquaintances are confused. An instruction. By Ethan, the Ezrahite

I will destroy the one who secretly slanders a friend. I will not allow the proud and haughty to prevail.
