Shemer was the owner of the hill purchased by Omri, on which Samaria was built. The name is also borne by a Merarite, an Asherite, and a Benjamite in genealogical records.
Shemer is principally associated with the account of Omri’s purchase of the hill and the establishment of Samaria.
The identification of Samaria’s name with Shemer is questioned in the supplied material because the mountain was already called Shomeron when Omri bought it. Another proposed explanation connects the name with “watch mountain.”
