وَيُرُونَ شَعْبِي التَّمْيِيزَ بَيْنَ الْمُقَدَّسِ وَالْمُحَلَّلِ، وَيُعَلِّمُونَهُمُ التَّمْيِيزَ بَيْنَ النَّجِسِ وَالطَّاهِرِ.
(صف٤٤ :٢٣ )

They are to teach my people the difference between the holy and the common and show them how to distinguish between the unclean and the clean.

(Ezekiel 44:23, NIV)
