This is background information. Some people who first read this book had probably heard of Kiriath Arba but did not know that it was the same as the city that they called Hebron. (See: [[rc://en/ta/man/translate/writing-background]])
These are the names of three Canaanite leaders of Hebron. Each leader represents his army. Alternate translation: "Sheshai, Ahiman, Talmai, and their armies" (See: [[rc://en/ta/man/translate/translate-names]] and [[rc://en/ta/man/translate/figs-metonymy]])
