TSK · Exodus 12:15

The uncircumcised male who is not circumcised in the flesh of his foreskin, that soul shall be cut off from his people. He has broken my covenant."

Seven days shall there be no yeast found in your houses, for whoever eats that which is leavened, that soul shall be cut off from the congregation of Israel, whether he be a foreigner, or one who is born in the land.

Seven days you shall eat unleavened bread, and in the seventh day shall be a feast to Yahweh.

Whoever compounds any like it, or whoever puts any of it on a stranger, he shall be cut off from his people.'"

You shall keep the Sabbath therefore; for it is holy to you. Everyone who profanes it shall surely be put to death; for whoever does any work therein, that soul shall be cut off from among his people.

"You shall not offer the blood of my sacrifice with leavened bread; neither shall the sacrifice of the feast of the Passover be left to the morning.

For as to the life of all flesh, its blood is with its life: therefore I said to the children of Israel, "You shall not eat the blood of any kind of flesh; for the life of all flesh is its blood. Whoever eats it shall be cut off."

On the fifteenth day of the same month is the feast of unleavened bread to Yahweh. Seven days you shall eat unleavened bread.

On the fifteenth day of this month shall be a feast: seven days shall unleavened bread be eaten.

You may not sacrifice the Passover within any of your gates, which Yahweh your God gives you;

The children of Israel who were present at Jerusalem kept the feast of unleavened bread seven days with great gladness; and the Levites and the priests praised Yahweh day by day, [singing] with loud instruments to Yahweh.

Then they understood that he didn't tell them to beware of the yeast of bread, but of the teaching of the Pharisees and Sadducees.

Meanwhile, when a multitude of many thousands had gathered together, so much so that they trampled on each other, he began to tell his disciples first of all, "Beware of the yeast of the Pharisees, which is hypocrisy.

Purge out the old yeast, that you may be a new lump, even as you are unleavened. For indeed Christ, our Passover, has been sacrificed in our place.
