Exodus 12:24

‘Now this day will be a memorial to you, and you shall celebrate it as a feast to Yahweh; throughout your generations you are to celebrate it as a perpetual statute.

“Therefore, you shall keep this statute at its appointed time from year to year.

“Then You performed signs and wonders against Pharaoh, Against all his servants and all the people of his land; For You knew that they acted presumptuously toward them, And made a name for Yourself as it is this day.

“In the first month, on the fourteenth day of the month, you shall have the Passover, a feast of seven days; unleavened bread shall be eaten.

Now the Passover and Unleavened Bread were two days away; and the chief priests and the scribes were seeking how, after seizing Him in secret, they might kill Him;

When he had seized him, he put him in prison, delivering him to four squads of soldiers to guard him, intending after the Passover to bring him out before the people.

By faith he kept the Passover and the sprinkling of the blood, so that he who destroyed the firstborn would not touch them.
