Fulltime - I posted that stuff though because it does make sense on time frame. If they were enslaved and released, then it would take them 3 to 5 days max to walk to the red sea. If Pharoh changed his mind and send an army on chariots, then it would mean it would be 2 or 3 days later and they would have caught up to them at the Red Sea.
Chariots would need roads, if no road to Palestine, as there would not be since supposedly that would be under control of the tough canannites then it wouldn't happen. But there was likely a road to the red sea due to close proximity to Cairo and for bringing in fish, etc.
Also having rechecked, in Ex 1:11 it says they build for them 'supply cities' Pithom and Raamses. Looking up the cities, this is supposedly some ruins of Pithom, which most definitely show bricks made from mud vs the limestone blocks from a quarry on the pyramids. A 10th century Jewish scholar supposedly identified Faiyum as the city of Pithom.
Some things to wonder....whoever wrote it all definitely would have had a good knowledge of those areas and the distances to make it up. And if all of it was made up, how did the Jewish people suddenly one day get duped into the passover and their deliverance from Egypt?
Seems like something had to happen, even if exaggerations. Similar to tell somebody a story and have them pass it down and whether the story is identical after 10 people, etc.
