Malachi 3:10 NIV

2 Chronicles 31:4-19 NIV
He ordered the people living in Jerusalem to give the portion due the priests and Levites so they could devote themselves to the Law of the Lord. As soon as the order went out, the Israelites generously gave the firstfruits of their grain, new wine, olive oil and honey and all that the fields produced. They brought a great amount, a tithe of everything. The people of Israel and Judah who lived in the towns of Judah also brought a tithe of their herds and flocks and a tithe of the holy things dedicated to the Lord their God, and they piled them in heaps. They began doing this in the third month and finished in the seventh month. When Hezekiah and his officials came and saw the heaps, they praised the Lord and blessed his people Israel. Hezekiah asked the priests and Levites about the heaps; and Azariah the chief priest, from the family of Zadok, answered, “Since the people began to bring their contributions to the temple of the Lord, we have had enough to eat and plenty to spare, because the Lord has blessed his people, and this great amount is left over.” Hezekiah gave orders to prepare storerooms in the temple of the Lord, and this was done. Then they faithfully brought in the contributions, tithes and dedicated gifts. Konaniah, a Levite, was the overseer in charge of these things, and his brother Shimei was next in rank. Jehiel, Azaziah, Nahath, Asahel, Jerimoth, Jozabad, Eliel, Ismakiah, Mahath and Benaiah were assistants of Konaniah and Shimei his brother. All these served by appointment of King Hezekiah and Azariah the official in charge of the temple of God. Kore son of Imnah the Levite, keeper of the East Gate, was in charge of the freewill offerings given to God, distributing the contributions made to the Lord and also the consecrated gifts. Eden, Miniamin, Jeshua, Shemaiah, Amariah and Shekaniah assisted him faithfully in the towns of the priests, distributing to their fellow priests according to their divisions, old and young alike. In addition, they distributed to the males three years old or more whose names were in the genealogical records —all who would enter the temple of the Lord to perform the daily duties of their various tasks, according to their responsibilities and their divisions. And they distributed to the priests enrolled by their families in the genealogical records and likewise to the Levites twenty years old or more, according to their responsibilities and their divisions. They included all the little ones, the wives, and the sons and daughters of the whole community listed in these genealogical records. For they were faithful in consecrating themselves. As for the priests, the descendants of Aaron, who lived on the farmlands around their towns or in any other towns, men were designated by name to distribute portions to every male among them and to all who were recorded in the genealogies of the Levites.

2 Corinthians 9:6-8 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. 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.

Deuteronomy 28:12 NIV
The Lord will open the heavens, the storehouse of his bounty, to send rain on your land in season and to bless all the work of your hands. You will lend to many nations but will borrow from none.

“‘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.

Matthew 6:33 NIV
But seek first his kingdom and his righteousness, and all these things will be given to you as well.

Nehemiah 12:44 NIV
At that time men were appointed to be in charge of the storerooms for the contributions, firstfruits and tithes. From the fields around the towns they were to bring into the storerooms the portions required by the Law for the priests and the Levites, for Judah was pleased with the ministering priests and Levites.

Nehemiah 13:10-13 NIV
I also learned that the portions assigned to the Levites had not been given to them, and that all the Levites and musicians responsible for the service had gone back to their own fields. So I rebuked the officials and asked them, “Why is the house of God neglected?” Then I called them together and stationed them at their posts. All Judah brought the tithes of grain, new wine and olive oil into the storerooms. I put Shelemiah the priest, Zadok the scribe, and a Levite named Pedaiah in charge of the storerooms and made Hanan son of Zakkur, the son of Mattaniah, their assistant, because they were considered trustworthy. They were made responsible for distributing the supplies to their fellow Levites.

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.
