When Joab saw that the front of the battle was against him before and behind, he chose of all the choice men of Israel, and put them in array against the Syrians:

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

So 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, was come unto Absalom, that Hushai said unto Absalom, God save the king, God save the king.

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