2 Samuel 12:14-16

King James Version

¹⁴ Howbeit, because by this deed thou hast given great occasion to the enemies of the Lord to blaspheme, the child also that is born unto thee shall surely die.

¹⁵ And Nathan departed unto his house. And the Lord struck the child that Uriah's wife bare unto David, and it was very sick.

¹⁶ David therefore besought God for the child; and David fasted, and went in, and lay all night upon the earth.
