The peninsula acquired the name Sinai in modern times due to the assumption that a mountain near Saint Catherine's Monastery is the Biblical Mount Sinai. However this assumption is contested. The name "Sinai" (, ) may have been derived from the ancient Mesopotamian moon-god Sin or from the Hebrew word "Seneh" ( ""). As both the moon-deity Sin is associated with the area, the ancient Egyptian moon-god Thoth is also is associated with Sin and worshipped widespread throughout the south tip of the Sinai Peninsula.
