I can remember being in Spain one year when i was about 17.
Lloret de Mar i think, where the Moon in the night sky appeared to be the size of a beach ball and really low on the horizon.
I just put it down to viewing the object from a different longitude and latitude but the thing appeared huge.
Comparatively speaking i would suggest the Moon generally appears to be the size of a volleyball or size 4 football here in the UK for the most part.
Haven't you ever seen a really big harvest moon? It can circle a whole building or look huge over the lake or cresting a mountain.

I don't know where you get the ice crystals thing, but yes I've seen the moon look much larger when it was low in the sky and thought the atmosphere was magnifying the size somehow. Then I read that was just an optical illusion and it only appeared bigger, but that appearance was an illusion. I didn't believe that at first, so I had to make some measurements, and sure enough, the measurements proved to me once again that we can't trust our eyes/brains completely, because they can fool us, and boy was I fooled. From your post, I see I'm not the only one. It's a very convincing optical illusion. Photographers can combine that "moon illusion" as it's called, with "forced perspective" to create dramatic images of the moon:

Lots of problems here. The translations don't agree. King James version mentions a sundial but it translates as 10 degrees, not steps.

Use you history..
Isaiah 38
This is the sign to you from the Lord that the Lord will do this thing that he has promised: See, I will
make the shadow cast by the declining sun on the dial of Ahaz turn back ten steps.” So the sun turned
back on the dial the ten steps by which it had declined
12 hours of light a day on a sundial
360 / 12 = 30)
one hour would be 30 steps..
ten steps would be aprox 20 mins...
The difference in speed between 365.2425 days per year and 360 days per year is equal to 20.9688
minutes per day (5.25 days X 24 hours X 60 minutes equals 7,560 minutes divided by 360 days equals
21 minutes per day
adds up pretty well eh..
King James Bible
Behold, I will bring again the shadow of the degrees, which is gone down in the sun dial of Ahaz, ten degrees backward. So the sun returned ten degrees, by which degrees it was gone down.
So unless someone has something to suggest the steps on the "stairway of Ahaz" are calibrated, I wouldn't assume it means 1 degree per step or any other calibrated value.
New International Version
I will make the shadow cast by the sun go back the ten steps it has gone down on the stairway of Ahaz.’” So the sunlight went back the ten steps it had gone down.
