25 Nadab son of Jeroboam began to reign over Israel in the second year of King Asa of Judah; he reigned over Israel two years. 26 He did what was evil in the sight of the Lord, walking in the way of his ancestor and in the sin that he caused Israel to commit. 27 Baasha 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 Nadab in the third year of King Asa of Judah, and succeeded him.

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.
