Malachi 3:10 (AMP)
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.

2 Corinthians 9:8 (AMP)
God is able to make all grace (every favor and earthly blessing) come to you in abundance, so that you may always and under all circumstances and whatever the need  be self-sufficient [possessing enough to require no aid or support and furnished in abundance for every good work and charitable donation].
