Need all christians' help

My turn to lead a Bible Study Night on Matthew Chp 4 in two weeks' time; read the Bible and some references, but still don't feel confident at all. Need help from you all in finding me some more on-line materials to dig out deeper meanings of Matthew Chp 4, and its connections with other chapters in both New & Old Testaments.

Thank you very much. Appreciate your great efforts.
