'Forgiveness' in the Bible

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

This is how it is to be done: every creditor is to give up his right to whatever he has let his neighbour have; he is not to make his neighbour, his countryman, give it back; because a general forgiveness has been ordered by the Lord.

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.
