Matthew Henry on 1 Kings 15:25–end
We are now to take a view of the miserable state of Israel, while the kingdom of Judah was happy under Asa's good government. It was threatened that they should be as a reed shaken in the water (Kg1 14:15), and so they were, when, during the single reign of Asa, the government of their kingdom was in six or seven different hands, as we find in this and the following chapter. Jeroboam was upon the throne in the beginning of his reign and Ahab at the end of it, and between them were Nadab, Baasha, Elah, Zimri, Tibni, and Omri, undermining and destroying one another. This they got by deserting the house both of God and of David. Here we have, 1. The ruin and extirpation of the family of Jeroboa…

John Gill on 1 Kings 15:31
Now the rest of the acts of Nadab, and all that he did,.... In his short reign, which yet were more than here related:

Keil & Delitzsch on 1 Kings 15:25-32
The Reign of Nadab lasted not quite two years, as he ascended the throne in the second year of Asa, and was slain in his third year.
Kg1 15:26-31
He walked in the ways of his father (Jeroboam) and in his sin, i.e., in the calf-worship introduced by Jeroboam (Kg1 12:28). When Nadab in the second year of his reign besieged Gibbethon, which the Philistines and occupied, Baasha the son of Ahijah, of the house, I the family or tribe, of Issachar, conspired against him and slew him, and after he became king exterminated the whole house of Jeroboam, without leaving a single soul, whereby the prediction of the prophet Ahijah (Kg1 14:10.) was fulfilled. Gibbethon, which was allotted to the Danites (J…
