Rav Leibtag is one of the pioneers of Torah education via the Internet. His weekly essays on Parshat Ha'shavua, read by literally thousands of subscribers world wide, introduce a vibrant analytical approach to thematic study of the Bible and reflect over twenty years of experience as a student and teacher at Yeshivat Har Etzion in Israel. He was the founder of the Yeshiva's Virtual Bet Midrash and more recently founded the Tanach Study Center, which contains a full archive of his lectures in various formats. In addition to his educational responsibilities at Har Etzion, Rav Leibtag also lectures at Yeshivat Shaalvim, Yeshivat ha'Kotel, Midreshet Lindenbaum, and Orot College for Women. He has delivered lectures and teacher workshops extensively in Israel and the Diaspora.
