So Jehovah assures us that once he forgives, he will never in the future act against us because of those sins. He does not rehash our sins in order to accuse us or punish us again and again.
فَهُوَ يُؤَكِّدُ لَنَا أَنَّهُ حِينَ يَغْفِرُ خَطَايَانَا ،‏ لَنْ يَتَّخِذَ أَبَدًا فِي ٱلْمُسْتَقْبَلِ إِجْرَاءً ضِدَّنَا بِسَبَبِهَا .‏
