During the First World War, numerous military chaplains of Jewish faith served in the ranks of the German army. The primary activity of the so-called field rabbis was to provide spiritual care for their fellow believers. In particular, they sought to reach soldiers by holding regular services, and distributing religious literature. One exceedingly useful measure therefor: the publication of "Sabbath Thoughts for Jewish Soldiers" - handy, printed brochures that reproduced the sermon that had been given. Usually based on a biblical verse that the field rabbis applied to the specific conditions of war, their main purpose was to convey to the uniformed audience the meaningfulness of wartime service with all its hardships as well as to strengthen the religious identity of German Jews. Thus, the "Sabbath Thoughts" are a unique source whose evaluation provides insightful information about the interpretation of the Holy Scripture under the auspices of military duty.
