2 Samuel 12:14-16

Young's Literal Translation

¹⁴ only, because thou hast caused the enemies of Jehovah greatly to despise by this thing, also the son who is born to thee doth surely die.'

¹⁵ And Nathan goeth unto his house, and Jehovah smiteth the lad, whom the wife of Uriah hath born to David, and it is incurable;

¹⁶ and David seeketh God for the youth, and David keepeth a fast, and hath gone in and lodged, and lain on the earth.
