Deuteronomy 15:10-14

You shall generously give to him, and your heart shall not be grudging when you give to him, because for this thing the Lord your God will bless you in all your work, and in all your undertakings.

For the poor will not cease to exist in the land; therefore I am commanding you, saying, ‘You shall fully open your hand to your brother, to your needy and poor in your land.’

“If your fellow countryman, a Hebrew man or woman, is sold to you, then he shall serve you for six years, but in the seventh year you shall set him free.

And when you set him free, you shall not send him away empty-handed.

You shall give generously to him from your flock, your threshing floor, and from your wine vat; you shall give to him as the Lord your God has blessed you.
