أَخْبَارِ ٱلْأَيَّامِ ٱلثَّانِي 35:6

وَٱذْبَحُوا ٱلْفِصْحَ وَتَقَدَّسُوا وَأَعِدُّوا إِخْوَتَكُمْ لِيَعْمَلُوا حَسَبَ كَلَامِ ٱلرَّبِّ عَنْ يَدِ مُوسَى».

So kill the passover, and sanctify yourselves, and prepare your brethren, that they may do according to the word of the LORD by the hand of Moses.
