'Kings' in the Bible

Now when Saul had taken the kingdom over Israel, he fought against all his enemies on every side, against Moab, and against the children of Ammon, and against Edom, and against the kings of Zobah, and against the Philistines: and whithersoever he turned himself, he put them to the worse.

Then Achish gave him Ziklag that day: wherefore Ziklag pertaineth unto the kings of Judah unto this day.
