حِزْقِيَال 3:9

قَدْ جَعَلْتُ جَبْهَتَكَ كَٱلْمَاسِ أَصْلَبَ مِنَ ٱلصَّوَّانِ، فَلَا تَخَفْهُمْ وَلَا تَرْتَعِبْ مِنْ وُجُوهِهِمْ لِأَنَّهُمْ بَيْتٌ مُتَمَرِّدٌ».

As an adamant harder than flint have I made thy forehead: fear them not, neither be dismayed at their looks, though they be a rebellious house.
