2 Samuel 12:19-23

When David saw them whispering, he realized what had happened. “Is the child dead?” he asked. “Yes,” they replied, “he is dead.” Then David got up from the ground, washed himself, put on lotions, and changed his clothes. He went to the Tabernacle and worshiped the LORD. After that, he returned to the palace and was served food and ate. His advisers were amazed. “We don’t understand you,” they told him. “While the child was still living, you wept and refused to eat. But now that the child is dead, you have stopped your mourning and are eating again.” David replied, “I fasted and wept while the child was alive, for I said, ‘Perhaps the LORD will be gracious to me and let the child live.’ But why should I fast when he is dead? Can I bring him back again? I will go to him one day, but he cannot return to me.”
