25 Now Nadab the son of Jeroboam became king over Israel in the second year of Asa king of Judah, and he reigned over Israel two years. 26 And he did evil in the sight of the Lord, and walked in the way of his father, and in his sin by which he had made Israel sin. 27 Then Baasha the son of Ahijah, of the house of Issachar, conspired against him. And Baasha killed him at Gibbethon, which belonged to the Philistines, while Nadab and all Israel laid siege to Gibbethon. 28 Baasha killed him in the third year of Asa king of Judah, and reigned in his place. 29 And it was so, when he became king, that he killed all the house of Jeroboam. He did not leave to Jeroboam anyone that breathed, until he had destroyed him, according to the word of the Lord which He had spoken by His servant Ahijah the Shilonite, 30 because of the sins of Jeroboam, which he had sinned and by which he had made Israel sin, because of his provocation with which he had provoked the Lord God of Israel to anger. 31 Now the rest of the acts of Nadab, and all that he did, are they not written in the book of the chronicles of the kings of Israel?

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.
