Why?

³⁹ Jesus left and made his way to the Mount of Olives, as was his custom, and the disciples followed him. ⁴⁰ When he arrived, he said to them, “Pray that you won’t give in to temptation.” ⁴¹ He withdrew from them about a stone’s throw, knelt down, and prayed. ⁴² He said, “Father, if it’s your will, take this cup of suffering away from me. However, not my will but your will must be done.” ⁴³ Then a heavenly angel appeared to him and strengthened him. ⁴⁴ He was in anguish and prayed even more earnestly. His sweat became like drops of blood falling on the ground. ⁴⁵ When he got up from praying, he went to the disciples. He found them asleep, overcome by grief. ⁴⁶ He said to them, “Why are you sleeping? Get up and pray so that you won’t give in to temptation.”
