'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 shrewd man.

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

Now it came about when Hushai the Archite, David’s friend, came to Absalom, that Hushai said to Absalom, “Long live the king! Long live the king!”

Absalom said to Hushai, “Is this your loyalty to your friend? Why did you not go with your friend?”
