2 Corinthians 9:6

The soul that blesses will be enriched, And he who waters will himself be watered.

He who is gracious to a poor man lends to Yahweh, And He will repay him for his bountiful deed.

He who is generous will be blessed, For he gives from his food to the poor.

So I regarded it necessary to encourage the brothers that they would go on ahead to you and arrange beforehand your previously promised blessing, so that the same would be ready as a blessing and not as a begrudging obligation.

Do not be deceived, God is not mocked, for whatever a man sows, this he will also reap.
