From XIII, " If thou preparest bread, take the first fruit and give according to the commandment.
Likewise when thou openest a jar of wine or of oil, take the first-fruit and give to the Prophets.
And of silver, and raiment, and every possession, take the first-fruit, as may seem good to thee, and give according to the commandment."

LMAO dude there are so many ministries dedicated to slamming the televangelists and the prosperity guys but how many of them realize that we've had this problem for 1800 years at least? "Gimme everything you get first, do what the Law of Moses says."
