اَلْخُرُوجُ 30:10

وَيَصْنَعُ هَارُونُ كَفَّارَةً عَلَى قُرُونِهِ مَرَّةً فِي ٱلسَّنَةِ. مِنْ دَمِ ذَبِيحَةِ ٱلْخَطِيَّةِ ٱلَّتِي لِلْكَفَّارَةِ مَرَّةً فِي ٱلسَّنَةِ يَصْنَعُ كَفَّارَةً عَلَيْهِ فِي أَجْيَالِكُمْ. قُدْسُ أَقْدَاسٍ هُوَ لِلرَّبِّ».

And Aaron shall make an atonement upon the horns of it once in a year with the blood of the sin offering of atonements: once in the year shall he make atonement upon it throughout your generations: it is most holy unto the LORD.
