25 Nadab, the son of Jeroboam, became king over Israel in the second year that Asa was king of Judah; and he was king of Israel for two years. 26 He did evil in the eyes of the Lord, copying the evil ways of his father, and the sin which he did and made Israel do. 27 And Baasha, the son of Ahijah, of the family of Issachar, made a secret design against him, attacking him at Gibbethon, a town of the Philistines; for Nadab and the armies of Israel were making war on Gibbethon. 28 In the third year of the rule of Asa, king of Judah, Baasha put him to death, and became king in his place. 29 And straight away when he became king, he sent destruction on all the offspring of Jeroboam; there was not one living person of all the family of Jeroboam whom he did not put to death, so the word of the Lord, which he said by his servant Ahijah the Shilonite, came about; 30 Because of the sins which Jeroboam did and made Israel do, moving the Lord, the God of Israel, to wrath. 31 Now the rest of the acts of Nadab, and all he did, are they not recorded in the book of the history 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.
