David's kindness to the Egyptian servant 30:11-15

David and his men were undoubtedly very angry and ready to kill anyone who proved to have had a hand in kidnapping their family members. To his credit David did not kill this Egyptian, as he planned to kill Nabal earlier. Instead he treated him kindly, in contrast to the Amalekite master's treatment of him, and won his favor and cooperation. Contrast Nabal's disdain for David, whom Nabal regarded as a runaway servant (25:10-11). The Egyptian wanted a guarantee of safety from David, as had Saul (cf. 24:2). Receiving this he agreed to lead David and his men to the Amalekites' camp.
