The Old Testament Tithing VS New Giving

This book is about the teaching of tithes and it storehouse, from I come to the Knowledge I have been searching for the storehouse in Malachi 3:10. Since I was 17 years old. And I am 65 and still can’t find it. The reason I can’t find it because I am a Gentile save by grace. And Malachi was given to the nation of Israel. Ye are cursed with a curse: for ye have robbed me, even this whole nation. Mal 3:9 (KJV). The Gentile had not the Law.
