'Mysql delete statement with limit

I'm trying to delete rows from a table but I get an error.

DELETE FROM `chat_messages` ORDER BY `timestamp` DESC LIMIT 20, 50;

I get this error at 50:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' 50' at line 1

No idea what's wrong.
