Q. Where did Jesus live in Egypt? Did they travel there on foot and how long did it take them to travel to Egypt?
A Dec. 13, 2016 comment on my post “How long did Jesus live in Egypt?” reports a visit to a home in Cairo that was supposedly the one in which the baby Jesus lived with his parents. This is, of course, possible. But I believe that Joseph, Mary, and Jesus would most likely have traveled to Alexandria for safety. There was a large Jewish colony in that city, and I even suspect that they had extended family or friends-of-friends who helped them settle there. But this is all speculative. The Bible simply reports that they went to Egypt, and we must rely on varying traditions for any further information.
The distance from Jerusalem to Alexandria is a little over 300 miles. In the time of Jesus, a “day’s journey” was considered to be about 20 miles. Assuming the family left from somewhere in Judea, it would have taken a little over two weeks for them to reach Alexandria (particularly considering that they were traveling with a young child).
