The letter was written on June 3rd, 1967, a few hours before the state of Israel declared war, on what was to become the six day war. Rav Meir describes in the letter the struggles of having a Yeshiva on the Gaza Border, in the then immigrant settlement of Netivot. He describes the time, as “this time of imminent danger”.
From the letter: “At this crisis in addition to studying day and night and bringing moral comfort to citizens of the town to prevent panic our Talmidim who intend to become the spiritual leaders for the entire Negev, now guard the town at night, render first aid to the citizens, dig trenches and assist the mayor in administration and the importance of this fortress of Torah on the Gaza Border is now recognized by all”.
