اَللَّاوِيِّينَ 5:3

أَوْ إِذَا مَسَّ نَجَاسَةَ إِنْسَانٍ مِنْ جَمِيعِ نَجَاسَاتِهِ ٱلَّتِي يَتَنَجَّسُ بِهَا، وَأُخْفِيَ عَنْهُ ثُمَّ عُلِمَ، فَهُوَ مُذْنِبٌ.

Or if he touch the uncleanness of man, whatsoever uncleanness it be that a man shall be defiled withal, and it be hid from him; when he knoweth of it, then he shall be guilty.
