Deuteronomy 15:7-11
7 If there is a poor man among your brothers in any of the towns of the land that the Lord your God is giving you, do not be hardhearted or tightfisted toward your poor brother.
8 Rather be openhanded and freely lend him whatever he needs.
9 Be careful not to harbor this wicked thought: "The seventh year, the year for canceling debts, is near," so that you do not show ill will toward your needy brother and give him nothing. He may then appeal to the Lord against you, and you will be found guilty of sin.
10 Give generously to him and do so without a grudging heart; then because of this the Lord your God will bless you in all your work and in everything you put your hand to.
11 There will always be poor people in the land. Therefore I command you to be openhanded toward your brothers and toward the poor and needy in your land.
Proverbs 11:24-25
24
One man gives freely, yet gains even more;
another withholds unduly, but comes to poverty.
25 A generous man will prosper;
he who refreshes others will himself be refreshed.
Proverbs 22:9
A generous man will himself be blessed, for he shares his food with the poor.
2 Corinthians 9:7
Each man should give what he has decided in his heart to give, not reluctantly or under compulsion, for God loves a cheerful giver.
