How did David go up the Mount of Olives as he fled from Absalom?

Answer: Weeping and barefoot

David went up the Mount of Olives weeping, with his head covered and walking barefoot; all the people with him wept as well.

“But David continued up the Mount of Olives, weeping as he went up. His head was covered, and he was walking barefoot. And all the people with him covered their heads and went up, weeping as they went.”— 2 Samuel 15:30 (BSB)
