How can I get the Name, Company, Phone Website and the description from the last (Most recent) 2 Task associated with the Lead. I do need all of the leads so Querying the Task Table and using Who does not work for me. 

I tried 

SELECT Id, Name, FirstName, LastName, Company, Website, Phone, (SELECT Description FROM Task limit 1 ) FROM Lead

Didn't understand relationship 'Task' in FROM part of query call. If you are attempting to use a custom relationship, be sure to append the '__r' after the custom relationship name. Please reference your WSDL or the describe call for the appropriate names.

How do you relate these two tables?
