'Friend' in the Bible

The Son of man came eating and drinking, and they say, Behold a man gluttonous, and a winebibber, a friend of publicans and sinners. But wisdom is justified of her children.

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

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, wherefore art thou come? Then came they, and laid hands on Jesus, and took him.
