Exodus 12:7

“And you shall take a bunch of hyssop and dip it in the blood which is in the basin, and touch some of the blood that is in the basin to the lintel and the two doorposts; and none of you shall go outside the doorway of his house until morning.

And they celebrated the Passover in the first month, on the fourteenth day of the month, at twilight, in the wilderness of Sinai; according to all that Yahweh had commanded Moses, so the sons of Israel did.

‘Then on the fourteenth day of the first month shall be the Passover of Yahweh.

Thus the sons of Israel who were present celebrated the Passover at that time, and the Feast of Unleavened Bread seven days.

“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.

Yahweh said to him, “Go through the midst of the city, even through the midst of Jerusalem, and put a mark on the foreheads of the men who sigh and groan over all the abominations which are being done in its midst.”

“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.
