'Circuits' in the Bible

This is the land that is left; all the circuits of the Philistines, and all Geshuri,

The wind goeth toward the south, and turneth about unto the north; it whirleth about continually, and the wind returneth again according to his circuits.

And also, what are ye to Me, O Tyre and Zidon, And all circuits of Philistia? Recompence are ye rendering unto Me? And if ye are giving recompence to Me, Swiftly, hastily, I turn back your recompence on your head.
