Gebul means border, boundary, territory, or limit. It appears about 240 times. It defines the edges of territories, the borders of nations, and the limits of the Promised Land as God designated them.
Boundaries reflect God's sovereign ordering of creation and nations. God sets the boundaries of the sea, of Israel's inheritance, and of the nations. Moving boundary markers was a serious sin (Deuteronomy 19:14), violating God's established order of justice and inheritance.
