Luke 22: 39-44 (ESV)
39 And he came out and went, as was his custom, to the Mount of Olives, and the disciples followed him. 40 And when he came to the place, he said to them, “Pray that you may not enter into temptation.” 41 And he withdrew from them about a stone's throw, and knelt down and prayed, 42 saying, “Father, if you are willing, remove this cup from me. Nevertheless, not my will, but yours, be done.” 43 And there appeared to him an angel from heaven, strengthening him. 44 And being in agony he prayed more earnestly; and his sweat became like great drops of blood falling down to the ground.
