Malachi 3:10-15

Bring all the tithes (the whole tenth of your income) into the storehouse, that there may be food in My house, and prove Me now by it, says the Lord of hosts, if I will not open the windows of heaven for you and pour you out a blessing, that there shall not be room enough to receive it. [Mal. 2:2.] And I will rebuke the devourer [insects and plagues] for your sakes and he shall not destroy the fruits of your ground, neither shall your vine drop its fruit before the time in the field, says the Lord of hosts. And all nations shall call you happy and blessed, for you shall be a land of delight, says the Lord of hosts. Your words have been strong and hard against Me, says the Lord. Yet you say, What have we spoken against You? You have said, It is useless to serve God, and what profit is it if we keep His ordinances and walk gloomily and as if in mourning apparel before the Lord of hosts? And now we consider the proud and arrogant to be happy and favored; evildoers are exalted and prosper; yes, and when they test God, they escape [unpunished].
