'Pardon' in the Bible

Forsake doth the wicked his way, And the man of iniquity his thoughts, And he returneth to Jehovah, and He pitieth him, And unto our God for He multiplieth to pardon.

And they do not teach any more Each his neighbour, and each his brother, Saying, Know ye Jehovah, For they all know Me, from their least unto their greatest, An affirmation of Jehovah; For I pardon their iniquity, And of their sin I make mention no more.
