Genesis 36:24

And these are the children of Zibeon; both Ajah, and Anah: this was that Anah that found the mules in the wilderness, as he fed the asses of Zibeon his father.

Cross-reference

In 1 Chronicles 1:40, the same Horite genealogy lists Anah as son of Zibeon — Chronicles reproduces this ancestral record directly.
