'Friend' in the Bible

The Son of man came eating and drinking, and they say, Behold, a gluttonous man and a winebibber, a friend of publicans and sinners! And wisdom is justified by her works.

But he answered and said to one of them, Friend, I do thee no wrong: didst not thou agree with me for a shilling?

and he saith unto him, Friend, how camest thou in hither not having a wedding-garment? And he was speechless.

And Jesus said unto him, Friend, do that for which thou art come. Then they came and laid hands on Jesus, and took him.
