'Kings' in the Bible

And Saul took the kingdom over Israel, and fought against all his enemies round about, 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 discomfited them.

And Achish gave him Ziklag that day; therefore Ziklag belongs to the kings of Judah to this day.
