'Friend' in the Bible

If I have rewarded evil to my friend,Or have plundered him who without cause was my adversary,

He does not slander with his tongue,Nor does evil to his neighbor,Nor takes up a reproach against his friend;

I went about as though it were my friend or brother;I bowed down mourning, as one who sorrows for a mother.

Even my close friend in whom I trusted,Who ate my bread,Has lifted up his heel against me.

But it is you, a man my equal,My companion and my familiar friend;

You have removed lover and friend far from me;My acquaintances are in darkness.
