'Half' in the Bible

Only King Og of Bashan was left of the remaining Rephaites. (It is noteworthy that his sarcophagus was made of iron. Does it not, indeed, still remain in Rabbath of the Ammonites? It is thirteen and a half feet long and six feet wide according to standard measure.)

This is the land we brought under our control at that time: The territory extending from Aroer by the Wadi Arnon and half the Gilead hill country with its cities I gave to the Reubenites and Gadites.

The rest of Gilead and all of Bashan, the kingdom of Og, I gave to half the tribe of Manasseh. (All the region of Argob, that is, all Bashan, is called the land of Rephaim.

Then we took their land and gave it as an inheritance to Reuben, Gad, and half the tribe of Manasseh.
