TSK · Exodus 30:38

For seven days you must eat bread made without yeast. Surely on the first day you must put away yeast from your houses because anyone who eats bread made with yeast from the first day to the seventh day will be cut off from Israel.

So you must keep the Sabbath, for it is holy for you. Everyone who defiles it must surely be put to death; indeed, if anyone does any work on it, then that person will be cut off from among his people.

but has not brought it to the entrance of the Meeting Tent to present it as an offering to the LORD before the tabernacle of the LORD. He has shed blood, so that man will be cut off from the midst of his people.

But the man who is ceremonially clean, and was not on a journey, and fails to keep the Passover, that person must be cut off from his people. Because he did not bring the LORD’s offering at its appointed time, that man must bear his sin.
