“She summoned Barak son of Abinoam, of Kedesh in Naftali, and said to him, “Hashem, the God of Yisrael, has commanded: Go, march up to Mount Tavor, and take with you ten thousand men of Naftali and Zevulun” JUDGES 4:6 (The Israel Bible™)

The prophetess and judge Devora instructs Barak in God’s name that he is to “march up to Mount Tavor” and take ten thousand soldiers with him, to prepare to fight the enemy Sisera. Metzudat David points out that taking the soldiers does not mean he was to simply draft them into service. Rather, it means to “draw at their hearts,” so that they would overcome their natural fear of Sisera and fight courageously. Rabbi Shlomo Aviner notes that this teaches us an important lesson, which remains relevant to this day: the importance of paying attention to the emotional state of the soldiers of Israel. He writes, “The secret weapon of the Israeli Defense Forces is their morale, strength and courage.”
