Commento su I Cronache 4:15

Because he turned away (שֶׁפָּנָה from the counsel of the spies.” Now do not wonder that the family of Caleb the son of Hezron, was already traced, for this is the manner [in which this book is written]: he traces part of the lineage, skips to another family, and then returns to the first family.

and the sons of Elah: Uknaz That was his name: Uknaz.
