KJV
Howbeit in [the business of] the
ambassadors of the princes of Babylon, who sent unto him to inquire 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.
BSB
And so when ambassadors of the rulers of Babylon were sent to him to inquire about the wonder that had happened in the land, God left him alone to test him, that He might know all that was in Hezekiah’s heart.
