Arba
Easton's Dictionary
Four, a giant, father of Anak. From him the city of Hebron derived its name of Kirjath-arba, i.e., the city of Araba (Josh. 14:15; 15:13; 21:11; Gen. 13:18; 23:2). (See HEBRON.)

ar'-ba ('arba`, "four"): Variously described as "the greatest man among the Anakim" (Jos 14:15), "the father of Anak" (Jos 15:13), "the father of Anok" (Jos 21:11 margin). Thus he seems to have been regarded as the ancestor of the Anakim, and as the most famous hero of that race. He was the reputed founder of the city called after him, on the site of which Hebron was built (Jos 21:11).
