Deuteronomy 15:10-13 New International Version (NIV)

10. Give generously to them 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 fellow Israelites who are poor and needy in your land.

12. If any of your people—Hebrew men or women—sell themselves to you and serve you six years, in the seventh year you must let them go free.

13. And when you release them, do not send them away empty-handed.
