Proverbs 3:9-10 (NIV)

2 Corinthians 9:6-8 (NIV)

Generosity Encouraged

⁶ Remember this: Whoever sows sparingly will also reap sparingly, and whoever sows generously will also reap generously. ⁷ 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. ⁸ And God is able to bless you abundantly, so that in all things at all times, having all that you need, you will abound in every good work.

Malachi 3:6-10 (NIV)

Breaking Covenant by Withholding Tithes

⁶ “I the Lord do not change. So you, the descendants of Jacob, are not destroyed. ⁷ Ever since the time of your ancestors you have turned away from my decrees and have not kept them. Return to me, and I will return to you,” says the Lord Almighty.

“But you ask, ‘How are we to return?’

⁸ “Will a mere mortal rob God? Yet you rob me.

“But you ask, ‘How are we robbing you?’

“In tithes and offerings. ⁹ You are under a curse—your whole nation—because you are robbing me. ¹⁰ 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.

Nehemiah 10:35 (NIV)

³⁵ “We also assume responsibility for bringing to the house of the Lord each year the firstfruits of our crops and of every fruit tree.
