Divrey Hayamim Bais 32:30-32

Orthodox Jewish Bible

³⁰ This same Chizkiyahu also covered over the upper source of the Gichon Spring and tunneled it straight down to the west side of Ir Dovid. Chizkiyahu prospered in all his works.

³¹ Howbeit in the business of the ambassadors of the sarim of Babylon, who sent unto him to inquire of the mofet that was done in HaAretz, HaElohim left him, to test him, that He might know all that was in his lev.

³² Now the rest of the acts of Chizkiyahu, and his acts of chesed, hinei, they are written in the Chazon Yeshayahu ben Amoz HaNavi, and in the Sefer Melachim of Yehudah and Yisroel.
