Deuteronomy 9:2
A people great and tall, the children of the Anakims, whom thou knowest, and of whom thou hast heard say, Who can stand before the children of Anak! (Deuteronomy 9:2)
Children of Anak.
 After the Israelite conquest none of the Anakim remained in Judah, but a small remnant survived in Philistia (Joshua 11:22; 2 Sam. 21:16; 1 Chron. 20:4). It is thought that Goliath was a descendant of the Anakim (Num. 13:33; Joshua 11:22; 1 Sam. 17:4).
Anakims.
 Literally, “the long-necked ones.” They appear to have descended from Anak. Arba, founder of Hebron (Joshua 14:15; 15:13), was a chief of the Anakim. They were scattered over the hill country of Judah (see Num. 13:22, 28, 33).
