tithes and offerings

Bring the full tithe into the storehouse, that there may be food in my house. And thereby put me to the test, says the Lord of hosts, if I will not open the windows of heaven for you and pour down for you a blessing until there is no more need. I will rebuke the devourer for you, so that it will not destroy the fruits of your soil, and your vine in the field shall not fail to bear, says the Lord of hosts. Then all nations will call you blessed, for you will be a land of delight, says the Lord of hosts.
Malachi 3:10-12
Through the tithe, God took care of His people—and through the act of generous giving, God continues to bless His people.
