Deuteronomy 14:22-26
22 You shall surely tithe all the increase of your seed, that which comes out of the field year by year. 23 You shall eat before Yahweh your God, in the place which he chooses to cause his name to dwell, the tithe of your grain, of your new wine, and of your oil, and the firstborn of your herd and of your flock; that you may learn to fear Yahweh your God always. 24 If the way is too long for you, so that you are not able to carry it because the place which Yahweh your God shall choose to set his name there is too far from you, when Yahweh your God blesses you, 25 then you shall turn it into money, bind up the money in your hand, and shall go to the place which Yahweh your God shall choose. 26 You shall trade the money for whatever your soul desires: for cattle, or for sheep, or for wine, or for strong drink, or for whatever your soul asks of you. You shall eat there before Yahweh your God, and you shall rejoice, you and your household.
Luke 21:1-4
21 He looked up and saw the rich people who were putting their gifts into the treasury. 2 He saw a certain poor widow casting in two small brass coins.[a]3 He said, “Truly I tell you, this poor widow put in more than all of them, 4 for all these put in gifts for God from their abundance, but she, out of her poverty, put in all that she had to live on.”
2 Corinthians 9:6-8
6 Remember this: he who sows sparingly will also reap sparingly. He who sows bountifully will also reap bountifully. 7 Let each man give according as he has determined in his heart, not grudgingly or under compulsion, for God loves a cheerful giver. 8 And God is able to make all grace abound to you, that you, always having all sufficiency in everything, may abound to every good work.
Malachi 3:8-11
8 Will a man rob God? Yet you rob me! But you say, ‘How have we robbed you?’ In tithes and offerings. 9 You are cursed with the curse; for you rob me, even this whole nation. 10 Bring the whole tithe into the storehouse, that there may be food in my house, and test me now in this,” says Yahweh of Armies, “if I will not open you the windows of heaven, and pour you out a blessing, that there will not be room enough for. 11 I will rebuke the devourer for your sakes, and he shall not destroy the fruits of your ground; neither shall your vine cast its fruit before its time in the field,” says Yahweh of Armies.
