'Kings' in the Bible

and Saul captured the kingdom over Israel, and he fighteth round about against all his enemies, against Moab, and against the Bene-Ammon, and against Edom, and against the kings of Zobah, and against the Philistines, and whithersoever he turneth he doth vex them.

And Achish giveth to him in that day Ziklag, therefore hath Ziklag been to the kings of Judah till this day.
