'Friend' in the Bible

Now Amnon had a friend whose name [was] Jonadab the son of Shimeah, the brother of David. (Now Jonadab [was] a very crafty man.)

So Hushai the friend of David came to the city [as] Absalom was entering Jerusalem.

When Hushai the Arkite the friend of David came to Absalom, Hushai said to Absalom, "[Long] live the king, [long] live the king!"

Absalom said to Hushai, "This [is] your loyal love with your friend? Why did you not go with your friend?"
