I was reading Isaiah 43 and came across this passage concerning the return of the exiles from Babylon sounds a lot like Exodus with the safe passage through water and being saved from Egypt. What’s your view on the prophetic works being used to inspire parts of the Exodus story?

You speak of why we might consider Mark written at a later date - my question is "Isn't the existence in Gospel of Mark of narrative around several delays of the Parousia mean that the gospel is initially much earlier, but then interpolated on this subject to correct previous failure? i.e., can only have previous failure if those bits were written and included much earlier? How does this impact the history of Mark’s production and its timing?

(Plus I read the Nativity stories of Matthew and Luke from my work in progress, The Heresy of Paraphrase: An Interpretive Paraphrase of the Gospels.)
