'Release' in the Bible

The word which came to Jeremiah from the Lord after King Zedekiah had made a covenant with all the people who were in Jerusalem to proclaim release to them:

Although recently you had turned and done what is right in My sight, each man proclaiming release to his neighbor, and you had made a covenant before Me in the house which is called by My name.

“Therefore thus says the Lord, ‘You have not obeyed Me in proclaiming release each man to his brother and each man to his neighbor. Behold, I am proclaiming a release to you,’ declares the Lord, ‘to the sword, to the pestilence and to the famine; and I will make you a terror to all the kingdoms of the earth.
