In 36:21, Ezer is identified as a Horite chief and son of Seir — the ancestor whose sons are being listed here.

In 1 Chronicles 1:42, the same three sons of Ezer appear — Akan is rendered 'Jaakan,' a variant spelling.

In 1 Chronicles 1:38, Ezer appears among Seir's seven sons, confirming his place in the Horite genealogy.

In Numbers 33:31, 'Bene-jaakan' (sons of Jaakan) likely traces back to this Akan/Jaakan, linking Horite lineage to Israel's route.
