The Sabbath Year, The Release From Bondage

At the end of every seven years there is to be a general forgiveness of debt.
Deuteronomy 15:1

Deu 15:6 For the Lord your God will give you his blessing as he has said: you will let other nations have the use of your money, but you will not make use of theirs; you will be rulers over a number of nations, but they will not be your rulers.
Deu 15:7 If in any of your towns in the land which the Lord your God is giving you, there is a poor man, one of your countrymen, do not let your heart be hard or your hand shut to him;
Deu 15:8 But let your hand be open to give him the use of whatever he is in need of.

Deu 15:9 And see that there is no evil thought in your heart, moving you to say to yourself, The seventh year, the year of forgiveness is near; and so looking coldly on your poor countryman you give him nothing; and he will make an outcry to the Lord against you, and it will be judged as sin in you.

Deu 15:10 But it is right for you to give to him, without grief of heart: for because of this, the blessing of the Lord your God will be on all your work and on everything to which you put your hand.
