"Half Gilead" was possessed by Sihon, and the other half, separated from it by the river Jabbok, by Og, king of Bashan. The deep ravine of the river Hieromax (the modern Sheriat el-Mandhur) separated Bashan from Gilead, which was about 60 miles in length and 20 in breadth, extending from near the south end of the Lake of Gennesaret to the north end of the Dead Sea. Abarim, Pisgah, Nebo, and Peor are its mountains mentioned in Scripture.
In Hebrew, Gilead can also mean a memorial site, and is used to name boys, while "Gil" means joy in Hebrew and "ad" means forever, or eternity. Further, the word "Gil" in Hebrew can also be derived from the word for a "round" (stone), and therefore, Gilead can also mean a round (memorial) for eternity.
Gilead is also the title of the 2004 award-winning novel (2005 Pulitzer Prize for Fiction and the National Book Critics Circle Award) by American writer Marilynne Robinson.
It is also used in the titles and as the name of the main character of two Warhammer Fantasy novels by Dan Abnett and Nik Vincent: Gilead's Blood (published 2000) and the on-going serialized Black Library eBook sequel, Gilead's Curse (Hammer and Bolter, Issues 13-18+, published 2012).
The 1996 film The Spitfire Grill, a story of a young woman's transformation of a community and redemption of her own and her fellow townspeople's past, is set in the small town of Gilead, Maine. The 2001 musical of the same name set Gilead in Wisconsin, the location changed most likely due to the facet that Wisconsin was home to the composers.
