Exodus 12:4

2 “This month is the beginning of months for you; it shall be the first month of your year.

3 Tell the whole congregation of Israel that on the tenth day of this month each man must select a lamb for his family, one per household.

If the household is too small for a whole lamb, they are to share with the nearest neighbor based on the number of people, and apportion the lamb accordingly.

5 Your lamb must be an unblemished year-old male, and you may take it from the sheep or the goats.

6 You must keep it until the fourteenth day of the month, when the whole assembly of the congregation of Israel will slaughter the animals at twilight.

Here the Bible tells a story about someone else. Ask yourself what it can say to us today. Do read the surrounding verses too, because the context often says more than a single verse.
