25 Nadab son of Jeroboam began to rule over Israel in the second year of King Asa's reign in Judah. He reigned in Israel two years. 26 But he did what was evil in the Lord 's sight and followed the example of his father, continuing the sins that Jeroboam had led Israel to commit. 27 Then Baasha son of Ahijah, from the tribe of Issachar, plotted against Nadab and assassinated him while he and the Israelite army were laying siege to the Philistine town of Gibbethon. 28 Baasha killed Nadab in the third year of King Asa's reign in Judah, and he became the next king of Israel. 29 He immediately slaughtered all the descendants of King Jeroboam, so that not one of the royal family was left, just as the Lord had promised concerning Jeroboam by the prophet Ahijah from Shiloh. 30 This was done because Jeroboam had provoked the anger of the Lord, the God of Israel, by the sins he had committed and the sins he had led Israel to commit. 31 The rest of the events in Nadab's reign and everything he did are recorded in

Commentary on 1 Kings 15:25-34
(Read 1 Kings 15:25-34)
During the single reign of Asa in Judah, the government of Israel was in six or seven different hands. Observe the ruin of the family of Jeroboam; no word of God shall fall to the ground. Divine threatenings are not designed merely to terrify. Ungodly men execute the just judgments of God upon each other. But in the midst of dreadful sins and this apparent confusion, the Lord carries on his own plan: when it is fully completed, the glorious justice, wisdom, truth, and mercy therein displayed, shall be admired and adored through all the ages of eternity.
