'Friend' in the Bible

But Amnon had a friend, whose name was Jonadab, the son of Shimeah, David's brother; and Jonadab was a very subtle man.

So Hushai, David's friend, came into the city; and Absalom came into Jerusalem.

It happened, when Hushai the Archite, David's friend, had come to Absalom, that Hushai said to Absalom, "Long live the king! Long live the king!"

Absalom said to Hushai, "Is this your kindness to your friend? Why didn't you go with your friend?"
