Benno Jacob was a German Reform rabbi and Bible commentator. He earned a doctoral degree from the University of Breslau and served as a rabbi in a number of communities until 1929, when he turned his attentions to completing his Bible commentary. He was prominent in the fight against antisemitism, and he often wrote articles and spoke out publicly on the topic. He was also an opponent of Zionism, which he saw as leading to secularization and loss of faith. His work has not been translated from German. Those familiar with his insightful and often unique takes on biblical passages were in many cases introduced to his work by Nechama Leibowitz, who greatly admired his work and quoted his commentaries frequently.
