Malachi 3:8-10

Doth man deceive God? but ye are deceiving Me, And ye have said: ‘In what have we deceived Thee?’ The tithe and the heave-offering! With a curse ye are cursed! And Me ye are deceiving — this nation — all of it. Bring in all the tithe unto the treasure-house, And there is food in My house; When ye have tried Me, now, with this, Said JEHOVAH of Hosts, Do not I open to you the windows of heaven? Yea, I have emptied on you a blessing till there is no space.
