Ishmael’s descendants occupied the region from Havilah to Shur, which is east of Egypt in the direction of Asshur. There they lived in open hostility toward all their relatives.
Then Moses led the people of Israel away from the Red Sea, and they moved out into the desert of Shur. They traveled in this desert for three days without finding any water.
David and his men spent their time raiding the Geshurites, the Girzites, and the Amalekites—people who had lived near Shur, toward the land of Egypt, since ancient times.
Three days later, when David and his men arrived home at their town of Ziklag, they found that the Amalekites had made a raid into the Negev and Ziklag; they had crushed Ziklag and burned it to the ground.
