1 Chronicles 4:31

Their cities — Several of these cities though given to Simeon by Joshua, yet through the sloth or cowardice of that tribe, were not taken from the Philistines, until David's time, who took some of them; and, the Simeonites having justly forfeited their right to them by their neglect, gave them to his own tribe. For it is evident concerning Ziklag, one of them, that it was in the Philistines hands in David's time, and by them given to him, and by him annexed to the tribe of Judah, 1 Samuel 27:6.
