Interesting to note in these verses is the mention of Malchus. Found in all 4 gospels -
Matthew 26:51,
Mark 14:47,
Luke 22:50–51, and
John 18:10–1.
Apparently it was the last miracle that Jesus performed before his resurrection. [Luke 22:50-51] Perhaps this healing was recorded because Luke was a physician, IDK but it was significant because this servant of the high priest will always be remembered through biblical history.
8 Jesus answered, “I told you that I am he. If you are looking for me, then let these men go.” 9 This happened so that the words he had spoken would be fulfilled: “I have not lost one of those you gave me.”
This relates to
John 17:12
12 While I was with them, I kept them in your name, which you have given me. I have guarded them, and not one of them has been lost except the son of destruction, that the Scripture might be fulfilled.
11 Jesus commanded Peter, “Put your sword away! Shall I not drink the cup the Father has given me?”
Jesus prayer to his Father re: removing this cup but according to God's will, can be found in Matt26:39, Mark 143:36 and Luke 22:42 but in John he says:
John 17:13 says:
13 But now I am coming to you, and these things I speak in the world, that they may have my joy fulfilled in themselves.
Another interesting thing was the meaning of Malchus' name. In Hebrew it means: My King, Kingdom or counselor.
Perhaps that is why Jesus said: "Shall I not drink the cup the Father has given me?”
