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.
Beware lest you say in your heart, ‘My power and the might of my hand have gotten me this wealth.’ You shall remember the Lord your God, for it is he who gives you power to get wealth, that he may confirm his covenant that he swore to your fathers, as it is this day.
Income and expenditure you have to plan your finances and your budget how you navigate what you get each week or month and how spend it . There is a saying save something for a rainy day always have something to help you if ever you are in need.
Proverbs 10-22
The blessing of the Lord makes rich, and he adds no sorrow with it.
Proverbs 3-9-10
Honor the Lord with your wealth and with the firstfruits of all your produce; then your barns will be filled with plenty, and your vats will be bursting with wine.
