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

• The Gaon writes that each generation faces a challenge corresponding to one of the עשרת הדברות, and the final generation before Moshiach will face the challenge of לא תחמוד. 
• A close examination of the Aveira of the עץ הדעת and the evil of the נחש הקדמוני, which the Maharsha writes is the root of Amalek and Haman. 
• A discussion on the true חמדה (treasure/desire) of the world, based on the story of אחאב, and how to properly utilize the Middah of חמדה.
