2 Kings 15:23-26

23In the fiftieth year of Azariah king of Judah, Pekahiah son of Menahem became king over Israel in Samaria, and he reigned two years.

24But he did what was evil in Adonai’s eyes. He did not turn away from the sins of Jeroboam son of Nebat, which he caused Israel to commit.

25Then Pekah son of Remaliah, his aide, conspired against him and assassinated him in Samaria, in the castle of the royal palace, along with Argob, Arieh, and 50 Gileadite men. So he killed him and became king in his place.

26Now the rest of the acts of Pekahiah and all that he did, behold, they are written in the Book of the Chronicles of the Kings of Israel.
