'Half' in the Bible

All Israel, both foreigners and citizens, together with their elders, officers, and judges, stood on opposite sides of the Ark of the Covenant of the LORD. Half stood in front of Mount Gerizim and half stood in front of Mount Ebal, just as Moses, the LORD's servant had commanded at the first, so that they could bless the people of Israel.

Sihon king of the Amorites lived in Heshbon and ruled from Aroer, which is located on the edge of the Arnon River from the middle of the valley, including half of Gilead as far as Wadi Jabbok, the border of the Ammonites,

ruling over Mount Hermon, Salecah, and all of Bashan as far as the border of the descendants of Geshur, the descendants of Maacath, and half of Gilead to the border of Sihon king of Heshbon.

Their territory included Jazer, all the cities of Gilead, half the land of the Ammonites as far as Aroer which is located near Rabbah,

half of Gilead, including Ashtaroth and Edrei. The cities of the kingdom of Og in Bashan went to half of the descendants of Manasseh's son Machir, according to their tribes.
