Shiur from Rabbi Elimelech Kohn Ztl on פרשת תצוה. Discussed: 

• Sefer Zichron Meir explains how we can relate to Karbonos in modern times & why is a Karbon called a "Rayach Nechoch" (Pleasant Scent). 
• Why did Shaul Hamelech refer to the command of Hashem as a "Dybur" (word) while Shmuel Ha'navi called it "Kol"(sound)? What exactly was the sin of Shaul Hamelech in regard to not wiping out Amalek and how his descendant Esther atoned for it. 
• The Chofetz Chaim wonders how is it possible for us to bring Moshiach today if even greater generations couldn't.
