Since there is only 1 more verse in Chapter 2, lets take a look at it, and some of the other travel that was done here. According to this, Joseph took his wife and child to Nazareth. (BTW, another prophecy fulfilled!)
Based on the maps I found, Bethlehem to the edge of Egypt in those times was about 50-60 miles. Lets figure about 50 minutes a mile (remember, wife and infant, all their belongings, without pavement, on a donkey!), and I think I am being generous. 55*50 = 45.83 Hours…so saying they did 9 hour days, this makes 5 days travel (all your supplies, food, water, for 5 days etc…). Now he starts to return and has to change route to Nazareth.
Nazareth is about 70 miles north of Bethlehem…!
Lets approximate he gets 40 miles, gets scared, Angel warns in a dream, then he turns north: (40+70)*50 =~ 10 days
After about 4 days travel, for me to tell my wife. “Hey, I was warned not to go to Bethlehem, its still dangerous, lets travel 6 days North to Nazareth (which no-one likes, is my understanding)!” , may not have been met with the warmest of responses. “WHAT!!!, Do you see me here with this child? Do you even care about my saddle sores!?! What about Joppa, Lydda, Massada!?! Can you think of anywhere closer!?! Oh you had a dream? Oh…..well then lets follow your dream! I had a dream of pink elephants, we better be on our guard!” etc. etc. etc….
Let’s just reiterate…this was a man of GREAT faith!
(BTW, I am sure the mother of our Lord was very submissive & humble. Just making a point 😉 )
