“Kiriath-arba.” “Kiriath-arba” means “the town of Arba,” who was one of the Nephilim.

[For more on Arba and Kiriath-arba, see commentaries on Joshua 14:15 and 15:13. For more on the Nephilim, see commentary on Genesis 6:2.]

“and Abraham came to mourn for Sarah.” The Bible does not say where Abraham came from. It could have been from short or far. If Sarah had had a sickness that was causing her to go downhill, it seems Abraham would not have been far away. If she got sick quickly, he could have been away. The Bible just does not say.
