2 Samuel 12:16

12:16 Then David prayed to God for the child and fasted. He would even go and spend the night lying on the ground.

2 Samuel 12:19-23

12:19 When David saw that his servants were whispering to one another, he realized that the child was dead. So David asked his servants, “Is the child dead?” They replied, “Yes, he’s dead.” 12:20 So David got up from the ground, bathed, put on oil, and changed his clothes. He went to the house of the Lord and worshiped. Then, when he entered his palace, he requested that food be brought to him, and he ate.

12:21 His servants said to him, “What is this that you have done? While the child was still alive, you fasted and wept. Once the child was dead you got up and ate food!” 12:22 He replied, “While the child was still alive, I fasted and wept because I thought, ‘Perhaps the Lord will show pity and the child will live. 12:23 But now he is dead. Why should I fast? Am I able to bring him back? I will go to him, but he cannot return to me!’”
