Deuteronomy 26:10-15

26:10 So now, look! I have brought the first of the ground’s produce that you, Lord, have given me.” Then you must set it down before the Lord your God and worship before him. 26:11 You will celebrate all the good things that the Lord your God has given you and your family, along with the Levites and the resident foreigners among you.

Presentation of the Third-year Tithe

26:12 When you finish tithing all your income in the third year (the year of tithing), you must give it to the Levites, the resident foreigners, the orphans, and the widows so that they may eat to their satisfaction in your villages. 26:13 Then you shall say before the Lord your God, “I have removed the sacred offering from my house and given it to the Levites, the resident foreigners, the orphans, and the widows just as you have commanded me. I have not violated or forgotten your commandments. 26:14 I have not eaten anything when I was in mourning, or removed any of it while ceremonially unclean, or offered any of it to the dead; I have obeyed you and have done everything you have commanded me. 26:15 Look down from your holy dwelling place in heaven and bless your people Israel and the land you have given us, just as you promised our ancestors – a land flowing with milk and honey.”

Proverbs 3:9-10

3:9 Honor the Lord from your wealth

and from the first fruits of all your crops;

3:10 then your barns will be filled completely,

and your vats will overflow with new wine.

Malachi 3:10-11

3:10 “Bring the entire tithe into the storehouse so that there may be food in my temple. Test me in this matter,” says the Lord who rules over all, “to see if I will not open for you the windows of heaven and pour out for you a blessing until there is no room for it all. 3:11 Then I will stop the plague from ruining your crops, and the vine will not lose its fruit before harvest,” says the Lord who rules over all.
