'Friend' in the Bible

The Son of Man came eating and drinking, and they say, 'Behold, a man [who is] a glutton and a drunkard, a friend of tax collectors and sinners!' But wisdom is vindicated by her deeds."

But he answered one of them [and] said, 'Friend, I am not doing you wrong. Did you not come to an agreement with me for a denarius?

And he said to him, 'Friend, how did you come in here, not having wedding clothes?' But {he could say nothing}.

And Jesus said to him, "Friend, [do that] for which you have come." Then they came up [and] laid hands on Jesus and arrested him.
