25 And 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 And he did that which was evil in the sight of Jehovah, and walked in the way of his father, and in his sin wherewith he made Israel to sin. 27 And Baasha the son of Ahijah, of the house of Issachar, conspired against him; and Baasha smote him at Gibbethon, which belonged to the Philistines; for Nadab and all Israel were laying siege to Gibbethon. 28 Even in the third year of Asa king of Judah did Baasha slay him, and reigned in his stead. 29 And it came to pass that, as soon as he was king, he smote all the house of Jeroboam: he left not to Jeroboam any that breathed, until he had destroyed him; according unto the saying of Jehovah, which he spake by his servant Ahijah the Shilonite; 30 for the sins of Jeroboam which he sinned, and wherewith he made Israel to sin, because of his provocation wherewith he provoked Jehovah, the 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? 32 And there was war between Asa and Baasha king of Israel all their days.
33 In the third year of Asa king of Judah began Baasha the son of Ahijah to reign over all Israel in Tirzah, [and reigned] twenty and four years. 34 And he did that which was evil in the sight of Jehovah, and walked in the way of Jeroboam, and in his sin wherewith he made Israel to sin.

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.
