It's one of the most populated times in the whole city. And there are certain things that would be required if you wanted to go and be at the Temple. But your husband would really be the person required to show up in the Temple area, because he would be the one who would have to sacrifice the Pascal lamb that would be the center of the meal that you would have with your family. You'd go up, probably a week beforehand, to make sure that everybody would be in a state of purity. Purity is not an ethical metaphor in first century Judaism.
Purity is a state.
It's almost like a physical state that has metaphysical consequences. There's nothing morally wrong with you. It just means that while you're in that state, you shouldn't enter a zone of holiness. So pilgrims frequently went a week before Passover actually started so that they could undergo certain rituals of purification, and take part in the slaughter of the lambs for Passover that happens the night before Passover begins. And and then go back with people living in tents or people in outlying villages.
