I am going to try and answer this. I have not studied Kings, Yet. I did see 2 Kings 2:9 the double portion, so twice as much.
I confess, i used google here. I found this on a Berean study website. I am now very excited to study Kings. I am sure that I may be disqualified for my source being outside of the bible directly, meaning not finding the answer in the bible myself. However, again I am inspired to read and learn for myself.
