TSK · Deuteronomy 16:3

They will eat the meat the same night; they will eat it roasted over the fire with bread made without yeast and with bitter herbs.

This day will become a memorial for you, and you will celebrate it as a festival to the LORD– you will celebrate it perpetually as a lasting ordinance.

For seven days yeast must not be found in your houses, for whoever eats what is made with yeast– that person will be cut off from the community of Israel, whether a resident foreigner or one born in the land.

Also, take your flocks and your herds, just as you have requested, and leave. But bless me also.”

Moses said to the people,“Remember this day on which you came out from Egypt, from the place where you were enslaved, for the LORD brought you out of there with a mighty hand– and no bread made with yeast may be eaten.

Then on the fifteenth day of the same month will be the Feast of Unleavened Bread to the LORD; seven days you must eat unleavened bread.

And on the fifteenth day of this month is the festival. For seven days bread made without yeast must be eaten.

Say,‘This is what the king says,“Put this man in prison. Give him only a little bread and water until I safely return.”’”

He does amazing things that will be remembered; the LORD is merciful and compassionate.

“I will pour out on the kingship of David and the population of Jerusalem a spirit of grace and supplication so that they will look to me, the one they have pierced. They will lament for him as one laments for an only son, and there will be a bitter cry for him like the bitter cry for a firstborn.

So then, let us celebrate the festival, not with the old yeast, the yeast of vice and evil, but with the bread without yeast, the bread of sincerity and truth.

For sadness as intended by God produces a repentance that leads to salvation, leaving no regret, but worldly sadness brings about death.
