Written by Rabbi Moses ben Jacob Cordovero, among the major kabbalists of 16th-century Safed, Tomer Devorah is an ethical treatise that promotes imitatio Dei, imitating the Divine. Tomer Devorah presents the attributes of God and explains how to improve oneself by incorporating these attributes into one’s own life. Tomer Devorah was written in Hebrew and was first published in Venice in 1588.
