From the Hebrew Gibeah, meaning a curved round hill. But our translators have also employed the same English word for the very different term har , which has a much more extended sense than gibeah , meaning a whole district. For instance, in ( Exodus 24:4 ) the "hill" is the same which is elsewhere in the same chapter, vs. ( Exodus 24:12 Exodus 24:13 Exodus 24:18 ) etc., and book consistently and accurately rendered "mount" and "mountain." The "country of the hills," in ( 1:7 ; Joshua 9:1 ; 10:40 ; 11:16 ) is the elevated district of Judah, Benjamin and Ephraim, which is correctly called "the mountain" in the earliest descriptions of Palestine, ( Numbers 13:29 ) and in many subsequent passages.
