'Friend' in the Bible

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

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

And it came to pass, when Hushai the Archite, David's friend, came to Absalom, that Hushai said to Absalom, Long live the king! Long live the king!

And Absalom said to Hushai, Is this thy kindness to thy friend? why didst thou not go with thy friend?
