2 Chronicles 32:29-31

New Revised Standard Version, Anglicised

²⁹ He likewise provided cities for himself, and flocks and herds in abundance; for God had given him very great possessions. ³⁰ This same Hezekiah closed the upper outlet of the waters of Gihon and directed them down to the west side of the city of David. Hezekiah prospered in all his works. ³¹ So also in the matter of the envoys of the officials of Babylon, who had been sent to him to inquire about the sign that had been done in the land, God left him to himself, in order to test him and to know all that was in his heart.
