Exodus 13:6-7

Observe the entire and complete state here figured out of a sanctified soul. There must not be the least portion of leaven. So far from mixing it in the offering, it was not even to be seen. It is said that the Jews were so exceedingly tenacious on this point that before the feast day they searched the house diligently lest there should be anything leavened under their roof, which their eyes might behold on that day. Oh! that the Writer and Reader were both so earnest in their spiritual examinations. I would say with David, Lord! Cleanse thou me from secret faults. Psalms 19:12 .
