Accoring to the Book of Numbers, during the conquest of Canaan by the Israelites, Anak (spelt as both ענק and as הענק depending upon the reference) was a well known figure, and a forefather of the Anakites (aka. Anakim) who were strong and tall descendants of the Nephilim (Numbers 13:33). The text states that Anak was a Rephaite (Deuteronomy 2:11) and a son of Arba (Joshua 15:13). Etymologically, Anak means [long] neck.
