"Dead sea scrolls deception" by Michael Baigent.

- It is true that apologetic sites contain a list of "fixes" for many bible errors; it's also true that most of those fixes just replace one nonsense by another one. You already have to believe strongly in bible "inerrancy" for believing in those fixes. For this reason it's better to give a direct answer, instead of mentioning apologetic sites.

Dew comes from the atmosphere, so "falling from the sky" is a wrong expression, but not an outright error. As the bible was written, no one knew the cause of dew - so you can't blame them for a wrong formulation.

This is different with the wrong PI value. The Egyptians, Greeks and many other people at that time knew the correct approximation of Pi. So maybe the author of that text was not very educated. Apologetic sites offer the "explanation" that the circumference of Salomon's basin was measured on its inside, not on the outside - unfortunately this is nonsense, as no one would use the inside of a vessel for measuring its circumference. Besides, the bible text explicitly states that the outside is meant.
