Mount Gerizim (pron.: /ˈɡɛrɨˌzɪm/; Samaritan Hebrew Ar-garízim, Arabic جبل جرزيم Jabal Jarizīm, Tiberian Hebrew הַר גְּרִזִּים Har Gərizzîm, Standard Hebrew הַר גְּרִיזִּים Har Gərizzim) is one of the two mountains in the immediate vicinity of the West Bank city of Nablus (biblical Shechem), and forms the southern side of the valley in which Nablus is situated, the northern side being formed by Mount Ebal. The mountain is one of the highest peaks in the West Bank and rises to 2849 feet (881 m) above sea level, 228 feet (69.5 m) shorter than Mount Ebal. The mountain is particularly steep on the northern side, is sparsely covered at the top with shrubbery, and lower down there is a spring with a high yield of fresh water.
