I don`t see how it could be interpreted to mean it`s referring to an eclipse when it`s indicating the sun was about midday and didn`t set for a whole day .
To me that says the sun was visible in the sky for 18 hours and not the usual 12 hours.
The scripture also says the moon was visible in the daylight hours also which happens and it also remained motionless in the sky
.What the Bible writer didn`t appreciate Is that the sun does not revolve around the earth and for it to apparently stand still the earth would have had to stop rotating on it` axis which would have been catastrophic for all life on earth.
It just couldn`t happen
