His point I think is that Jesus was also God. He didn’t need anyone to tell him about John.
And the Bible says nothing about anyone pleading on John’s behalf. Don’t read into Scripture what isn’t there.....
I do not believe I am adding stuff. “Now when Jesus had heard that John was cast into prison”, So where did he hear it from? the line before it was the angles ministering right? So you tell me is it not safe to assume the two are related considering they are in conjunction with each other. If not they where did Jesus hear from?
