You Know That Rashi in Parshas VaYishlach...? By Rabbi Jack Abramowitz (SHMUEL1 CHAPTER 30)BONUS

(PLEASE LEARN FOR A REFUA SHELAMA FOR HARAV YOSEF SHALOM BEN CHAYA MUSHA) David and his men found the Amalekites partying and enjoying their booty. The Jewish army handily defeated them, except for 400 soldiers who fled on camels. (These 400 youths were descendants of the 400 men who deserted Esau rather than attack Jacob in Genesis chapter 33. They were spared as a reward for that - see Rashi on Gen. 33:16.) All the captives were recovered, safe and sound.
