2 Kings 15:23-26

23In the fiftieth year of Azariah’s reign over Judah, Pekahiah son of Menahem became king of Israel and reigned in Samaria two years. 24And he did evil in the sight of the LORD and did not turn away from the sins that Jeroboam son of Nebat had caused Israel to commit.

25Then his officer, Pekah son of Remaliah, conspired against him along with Argob, Arieh, and fifty men of Gilead. And at the citadel of the king’s palace in Samaria, Pekah struck down and killed Pekahiah and reigned in his place.

26As for the rest of the acts of Pekahiah, along with all his accomplishments, they are indeed written in the Book of the Chronicles of the Kings of Israel.
