There shall be no yeast seen with you in all your borders seven days; neither shall any of the flesh, which you sacrifice the first day at even, remain all night until the morning.
*'Seven days shall you eat matzah; even the first day you shall put away yeast out of your houses, for whoever eats leavened bread from the first day until the seventh day, that soul shall be cut off from Yisra'el.
Unleavened bread shall be eaten throughout the seven days; and no leavened bread shall be seen with you, neither shall there be yeast seen with you, in all your borders.
He spoke another parable to them. *The Kingdom of Heaven is like yeast, which a woman took, and hid in three measures of meal, until it was all leavened.*
