You must only sacrifice the Passover animal at the place where Yahweh your God chooses to have His name dwell. Do this in the evening as the sun sets at the same time of day you departed from Egypt.

In the morning you will say, ‘If only it were evening!’ and in the evening you will say, ‘If only it were morning!’—because of the dread you will have in your heart and because of what you will see.

No yeast is to be found anywhere in your territory for seven days, and none of the meat you sacrifice in the evening of the first day is to remain until morning.

When evening approaches, he must wash with water, and when the sun sets he may come inside the camp.
