2 Samuel 12:15-17

And Nathan departed unto his house. And Jehovah struck the child that Uriah’s wife bare unto David, and it was very sick. David therefore besought God for the child; and David fasted, and went in, and lay all night upon the earth. And the elders of his house arose, and stood beside him, to raise him up from the earth: but he would not, neither did he eat bread with them.
