Charles Ellicott Commentary 1 Kings 14:1

"At that time Abijah the son of Jeroboam fell sick." — 1 Kings 14:1 (ASV)

Abijah (“whose father is Jehovah”): The coincidence of names in the sons of Jeroboam and Rehoboam is curious. Possibly it may be more than coincidence, if (as seems likely) the births of both took place about the same time, when Jeroboam was in favour with Solomon.
