'Circuits' in the Bible

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

Going unto the south, and turning round unto the north, turning round, turning round, the wind is going, and by its circuits the wind hath returned.

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.
