Thematic Bible: Conducts an expedition against amalekites, misstates the facts to achish

Now David and his men went up and raided the Geshurites and the Girzites and the Amalekites, for they had been living [in] the land for a long time {in the direction of} Shur and {as far as} the land of Egypt. So David struck the land and did not leave a man or a woman alive; he took the sheep, the cattle, the donkeys, the camels, and the clothing. Then he returned and came to Achish. And Achish said, "Against whom have you raided today?" David said, "Against the Negev of Judah and against the Negev of the Jerahmeelites and against the Negev of the Kenites." read more.
And David did not leave alive a man or a woman to bring [them back] to Gath, thinking, "So that they will not report about us, saying, 'David did thus and so.'" Thus was his practice all the days that he lived in the countryside of [the] Philistines. And Achish trusted David, saying, "{He has made himself utterly hated} among his people in Israel, and he will be my servant forever."
