Matthew 26:40-43

Then he came to the disciples and found them sleeping. He asked Peter, “So, couldn’t you stay awake with me one hour? Stay awake and pray, so that you won’t enter into temptation. The spirit is willing, but the flesh is weak.” Again, a second time, he went away and prayed, “My Father, if this cannot pass unless I drink it, your will be done.” And he came again and found them sleeping, because they could not keep their eyes open.
