What is the Sweetwine bible in the novel, I’ll Give You the Sun?

The Sweetwine bible is a leather-bound handwritten volume of a collection of advice, wisdom, warnings, encouragements, and other similar writings meant to guide the reader through life, originally compiled and composed by Grandma Sweetwine. The bible explains things like gifts of oranges from boys means girls will grow to love them, and keeping an onion in a pocket will ward off illness. Jude is given the bible, and lives her life by its writings, consulting it frequently throughout the novel, and adding her own thoughts down as well.
