The key phrase in the scripture above is, the fact that God tells the Egyptians to; Render sacrifice and gift, and must make a vow to YHWH and pay it.
I did a calculation to see if it is possible to reach Amarna from The Edge of the Etham Wilderness in three days, a total of (approx) 170 miles.
At an average 3.5 miles per hour, it would take 3 days, travelling for 16 hours a day, and resting for 8 hours per day. Not an easy task, but these were a fit, strong nation, used to slaving for at least 16 hours at a time, and they were marching in battle formation, being driven out.. in a big hurry to escape. Ad to that, motivation, fear, and a massive amount of adrenalin, and I think even I could make it, and believe me, That would Be a Miracle.
But all this is still unproven. Take Moses, he was 80 years old, at the time of the exodus at (1513 BC) so he would have been born in 1553 BC and died in 1433BC aged 120. According to records Pharaoh Akhenaton started his reign in 1350 BC and died in 1332 BC.
(The dates for Akhenaton are (not conclusive) the dates for Moses are accurate to within a year or so. Moses died in 1433BC and Akhenaton- (ALLEGEDLY)- died in 1332BC 1433BC-1332BC =101years, this means Akhenaton died 101 years AFTER Moses, so IF the TIME of AKHEN-ATON is accurate, he does Not fit the time line profile, but fits a general profile.
Also back in the time of Jacob the, (True God) YHWH, was the witness to the covenant of Leban and Jacob (Israel),So Monotheism=ONE GOD was already established:) with the Heap of Rocks as a witness to the (True God). But even BEFORE THAT, SETH and his FAMILY were 'already' Calling on the NAME of YHWH.
When YHWH Gave MOSES the 10 Commandments, Gods name was WRITTEN IN THE STONE TABLETS..
But later when Copyists TRANSLATED the NAME and tried to Calve the 4 LETTERS into Stone, they kept chipping the letter U so to overcome the problem, they changed it to a V so it read like this; YHVH, instead of this;) YHUH. But that then changed the SOUND when SPOKEN.
So to COMPENSATE for the missing Uoo SOUND when SPOKEN, =it was a (Vah sound) and should be Uoo. They used a W =UU but it can still be the WRONG sound unless you KNOW to pronounce the W as UU. The SOUND WHEN SPOKEN IS YAHU.
But what about the Red Sea Crossing? to get to Amarna, Moses would have to cross the Red Sea, from East to West, it says in bible text that a Strong EAST wind, parted the sea, so travelling East to West would fit, and also, put the East Wind Behind them, pushing them along.
Work it out for Yourself and ASK; What is REALLY GOING ON.????
