Here are some key Bible verses about tithes:

1. Malachi 3:10 (NIV): “Bring the whole tithe into the storehouse, that there may be food in my house. Test me in this,” says the Lord Almighty, “and see if I will not throw open the floodgates of heaven and pour out so much blessing that there will not be room enough to store it.
2. Leviticus 27:30 (NIV): “A tithe of everything from the land, whether grain from the soil or fruit from the trees, belongs to the Lord; it is holy to the Lord.”
3. Deuteronomy 14:22-23 (NIV): “Be sure to set aside a tenth of all that your fields produce each year. Eat the tithe of your grain, new wine, and olive oil, and the firstborn of your herds and flocks in the presence of the Lord your God at the place he will choose as a dwelling for his Name, so that you may learn to revere the Lord your God always.”
4. 2 Corinthians 9:6-7 (NIV): “Remember this: Whoever sows sparingly will also reap sparingly, and whoever sows generously will also reap generously. Each of you should give what you have decided in your heart to give, not reluctantly or under compulsion, for God loves a cheerful giver.”
5. Proverbs 3:9-10 (NIV): “Honor the Lord with your wealth, with the firstfruits of all your crops; then your barns will be filled to overflowing, and your vats will brim over with new wine.”
6. Genesis 14:19-20 (NIV): “And he blessed Abram, saying, ‘Blessed be Abram by God Most High, Creator of heaven and earth. And blessed be God Most High, who delivered your enemies into your hand.’ Then Abram gave him a tenth of everything.”
7. Hebrews 7:1-2 (NIV): “This Melchizedek was king of Salem and priest of God Most High. He met Abraham returning from the defeat of the kings and blessed him, and Abraham gave him a tenth of everything. First, the name Melchizedek means ‘king of righteousness’; then also, ‘king of Salem’ means ‘king of peace.'”
8. Nehemiah 10:38 (NIV): “A priest of the descendants of Aaron is to accompany the Levites when they receive the tithe, and the Levites are to bring a tenth of the tithes up to the house of our God, to the storerooms of the treasury.”
   • Matthew 23:23 (NIV): “Woe to you, teachers of the law and Pharisees, you hypocrites! You give a tenth of your spices—mint, dill, and cumin. But you have neglected the more important matters of the law—justice, mercy, and faithfulness. You should have practiced the latter, without neglecting the former.
9. 1 Corinthians 16:2 (NIV): “On the first day of every week, each one of you should set aside a sum of money in keeping with your income, so that when I come no collections will have to be made.”
10. Deuteronomy 14:22-26 (NIV)”Be sure to set aside a tenth of all that your fields produce each year. Eat the tithe of your grain, new wine, and olive oil, and the firstborn of your herds and flocks in the presence of the Lord your God at the place he will choose as a dwelling for his Name, so that you may learn to revere the Lord your God always. If the distance is too great for you to carry your tithe (because the place where the Lord will choose to put his Name is too far away from you), then exchange your tithe for silver, and take the silver with you and go to the place the Lord your God will choose. Use the silver to buy whatever you like: cattle, sheep, wine or other fermented drink, or anything you wish. Then you and your household shall eat there in the presence of the Lord your God and rejoice.”
11. Deuteronomy 12:17-19 (NIV):
    “You must not eat in your own towns the tithe of your grain and new wine and olive oil, or the firstborn of your herds and flocks, or whatever you have vowed to give, or your freewill offerings or special gifts. Instead, you are to eat them in the presence of the Lord your God at the place the Lord your God will choose—you, your sons and daughters, your male and female servants, and the Levites from your towns—and you are to rejoice before the Lord your God in everything you put your hand to. Be careful not to neglect the Levites as long as you live in your land.”
12. Leviticus 23:39-40 (NIV):
    “So beginning with the fifteenth day of the seventh month, after you have gathered the crops of the land, celebrate the festival of the Lord for seven days; the first day is a day of sabbath rest, and the eighth day also is a day of sabbath rest. On the first day you are to take branches from luxuriant trees—from palms, willows, and other leafy trees—and rejoice before the Lord your God for seven days.”
13. Numbers 18:12-13 (NIV):
    “I give to the Levites all the tithes in Israel as their inheritance in return for the work they do while serving at the tent of meeting. From now on, the Israelites must not go near the tent of meeting, or they will bear the consequences of their sin and will die. It is the Levites who are to do the work at the tent of meeting and they bear the responsibility for any offenses they commit against it.”
