What is the prayer of Javis?
By this i believe you are referring to the "Prayer of Jabez" It is taken from a biblical passage in the first book of Paralipomenon or Chronicles. There was a very popular series of books/bible studies writen about this prayer and increasing personal wealth and happiness.
1 Chronicles 4:9-10: : And Jabez called on the God of Israel saying, "Oh that You would bless me indeed, and enlarge my territory, that Your hand would be with me, and that You would keep me from evil, that I may not cause pain!" So God granted him what he requested.
