Dr. Baruch Kvasnika is President of Jerusalem Seminary, which equips believers to understand their faith in and through the land of the Bible. His dissertation at The Hebrew University of Jerusalem was, "The Language of Practice: Hebraic Walking and Way Metaphors in First Century Greek Related to Conduct."
