Genesis

And it came to pass by the way in the inn, that the Lord met him, and sought to kill him.

Seven days shall ye eat unleavened bread; even the first day ye shall put away leaven out of your houses: for whosoever eateth leavened bread from the first day until the seventh day, that soul shall be cut off from Israel.

But the man that is clean, and is not in a journey, and forbeareth to keep the passover, even the same soul shall be cut off from among his people: because he brought not the offering of the Lord in his appointed season, that man shall bear his sin.

For by one offering he hath perfected for ever them that are sanctified.
