What does Joshua 15:13 mean?

Joshua gave Caleb, son of Jephunneh, a part of Judah’s land, just like the Lord had told him—Kiriath-arba, which is Hebron. Arba was the father of Anak. Joshua 15:13 - Modern Text Bible

(Caleb’s inheritance is repeated here, emphasizing that he got Hebron, a city named after a famous ancestor of the Anakim.)
