اَللَّاوِيِّينَ 5:1

«وَإِذَا أَخْطَأَ أَحَدٌ وَسَمِعَ صَوْتَ حَلْفٍ وَهُوَ شَاهِدٌ يُبْصِرُ أَوْ يَعْرِفُ، فَإِنْ لَمْ يُخْبِرْ بِهِ حَمَلَ ذَنْبَهُ.

And if a soul sin, and hear the voice of swearing, and is a witness, whether he hath seen or known of it; if he do not utter it, then he shall bear his iniquity.
