TSK · Exodus 34:25

They shall eat the flesh in that night, roasted with fire, and unleavened bread. They shall eat it with bitter herbs.

You shall eat nothing leavened. In all your habitations you shall eat unleavened bread.'"

If anything of the flesh of the consecration, or of the bread, remains to the morning, then you shall burn the remainder with fire: it shall not be eaten, because it is holy.

They shall leave none of it until the morning, nor break a bone of it. According to all the statute of the Passover they shall keep it.

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.
