25 Nadab the son of Jeroboam began to reign over Israel in the second year of Asa king of Judah, and he reigned over Israel two years. 26 He did what was evil in the sight of the Lord and walked in the way of his father, and in his sin which he made Israel to sin. 27 Baasha the son of Ahijah, of the house of Issachar, conspired against him. And Baasha struck him down at Gibbethon, which belonged to the Philistines, for Nadab and all Israel were laying siege to Gibbethon. 28 So Baasha killed him in the third year of Asa king of Judah and reigned in his place. 29 And as soon as he was king, he killed all the house of Jeroboam. He left to the house of Jeroboam not one that breathed, until he had destroyed it, according to the word of the Lord that he spoke by his servant Ahijah the Shilonite. 30 It was for the sins of Jeroboam that he sinned and that he made Israel to sin, and because of the anger to which he provoked the Lord, the God of Israel. 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.
