2 Samuel 12:15-17

Then Nathan went [back] to his home. A nd the LORD struck the child that Uriah’s widow bore to David, and he was very sick. David therefore appealed to God for the child [to be healed]; and David fasted and went in and lay all night on the ground. The elders of his household stood by him [in the night] to lift him up from the ground, but he was unwilling [to get up] and would not eat food with them.
