2 Chronicles 27:7
Rahlfs Septuagint (1935) · Berean Standard Bible
καὶ οἱ λοιποὶ λόγοι Ιωαθαμ καὶ ὁ πόλεμος καὶ αἱ πράξεις αὐτοῦ ἰδοὺ γεγραμμένοι ἐπὶ βιβλίῳ βασιλέων Ιουδα καὶ Ισραηλ
As for the rest of the acts of Jotham, along with all his wars and his ways, they are indeed written in the Book of the Kings of Israel and Judah.
