Show you? What is your intention here? Are you desperately trying to say that an angel of the Lord is NOT an angel of the Lord? I don't get your persistence. As I said in the beginning, you CAN OVER-THINK these things.
Your objection is that this occurrence is just another angel when He speaks as God in His own right. Other angels recorded in scripture don't. You say it isn't an occurrence of a theophany or Christophany. 'The angel of the Lord' reference doesn't occur in the NT.
