Anak is identified as the father of the Anakim and as the son of Arba. His name is associated with the formidable people who occupied the southern hill country of Canaan, especially the region of Hebron.
Anak appears in connection with the Anakim and with Arba, after whom Hebron was called the city of Arba. The biblical references identify him as the ancestor or namesake of that people.
The name is explained as meaning “long-necked.” Hebron was particularly associated with Anak and his descendants.
