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?
Sounds like it was common knowledge. Could have heard it in the market place.
Interceding indicates a go-between making an argument, or a plea. Simply hearing that “something” has happened is simply that, hearing something.
Answered part of my own question, Angels ministering and the message John was in prison. These are not related in time. They are separate.
However the question is still open on what were they ministering. A Minister reports back to the leader and represents them IE intersession.
