Exodus 34:18

⁶On the fifteenth day of the same month is the feast of unleavened bread to the LORD. Seven days you shall eat unleavened bread.

⁴Today you go out in the month Abib.

¹Observe the month of Abib, and keep the Passover to the LORD your God; for in the month of Abib the LORD your God brought you out of Egypt by night. ²You shall sacrifice the Passover to the LORD your God, of the flock and the herd, in the place which the LORD shall choose to cause his name to dwell there. ³You shall eat no leavened bread with it. You shall eat unleavened bread with it seven days, even the bread of affliction (for you came out of the land of Egypt in haste) that you may remember the day when you came out of the land of Egypt all the days of your life. ⁴No yeast shall be seen with you in all your borders seven days; neither shall any of the meat, which you sacrifice the first day at evening, remain all night until the morning.

⁶Seven days you shall eat unleavened bread, and in the seventh day shall be a feast to the LORD. ⁷Unleavened bread shall be eaten throughout the seven days; and no leavened bread shall be seen with you. No yeast shall be seen with you, within all your borders.

³When he saw that it pleased the Jews, he proceeded to seize Peter also. This was during the days of unleavened bread.

¹It was now two days before the Passover and the Feast of Unleavened Bread, and the chief priests and the scribes sought how they might seize him by deception and kill him.

¹⁵“‘Seven days you shall eat unleavened bread; 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 Israel. ¹⁶In the first day there shall be to you a holy convocation, and in the seventh day a holy convocation; no kind of work shall be done in them, except that which every man must eat, only that may be done by you. ¹⁷You shall observe the feast of unleavened bread; for in this same day I have brought your armies out of the land of Egypt. Therefore you shall observe this day throughout your generations by an ordinance forever. ¹⁸In the first month, on the fourteenth day of the month at evening, you shall eat unleavened bread, until the twenty first day of the month at evening. ¹⁹There shall be no yeast found in your houses for seven days, for whoever eats that which is leavened, that soul shall be cut off from the congregation of Israel, whether he is a foreigner, or one who is born in the land. ²⁰You shall eat nothing leavened. In all your habitations you shall eat unleavened bread.’”

¹⁵You shall observe the feast of unleavened bread. Seven days you shall eat unleavened bread, as I commanded you, at the time appointed in the month Abib (for in it you came out of Egypt), and no one shall appear before me empty.

¹Now the feast of unleavened bread, which is called the Passover, was approaching.

²“This month shall be to you the beginning of months. It shall be the first month of the year to you.
