Can someone direct me to where it is mentioned in the bible about watching for changes in trees and maybe fruit and such?  It was to be a sign to us.

I have fruit that has always been harvested in Oct.  Last year it was ready for picking mid Sept.  This year, it is going to be ready by mid to the end of August.  The birds are eating my fruit (prickly pear) that is not even near ripe.

My neighbor has grapes, had!  They too were not ready to be harvested and ripening to soon.  The birds ate them all.

If you can direct me to the book in the bible, I have very good bible(Haydock) with commentary.
