2 Chronicles 32:31
31 Howbeit in the business of the ambassadorsl of the princes of Babylon, who sent unto him to enquire of the wonder that was done in the land, God left him, to try him, that he might know all that was in his heart.
2 Chr. 32:31. "That He might know all that was in his heart." By this, together with verses 2 Chronicles 32:25; 2 Chronicles 32:26, it appears that Hezekiah had much sin in his heart, though, as he pleads with God in the time of his sickness, he had walked before God in truth and with a perfect heart. See also 2 Kings 18:3; 2 Kings 18:5; 2 Kings 18:6.
