اَلْخُرُوجُ 13:7

فَطِيرٌ يُؤْكَلُ ٱلسَّبْعَةَ ٱلْأَيَّامِ، وَلَا يُرَى عِنْدَكَ مُخْتَمِرٌ، وَلَا يُرَى عِنْدَكَ خَمِيرٌ فِي جَمِيعِ تُخُومِكَ.

Unleavened bread shall be eaten seven days; and there shall no leavened bread be seen with thee, neither shall there be leaven seen with thee in all thy quarters.
