July 18, 2025, Friday of the 15th week in ordinary time.

A reading from the book of Exodus.

Although Moses and Aaron performed various wonders in Pharaoh's presence,

the Lord made Pharaoh obstinate,

and he would not let the children of Israel leave his land.

The Lord said to Moses and Aaron in the land of Egypt,

This month shall stand at the head of your calendar.

You shall reckon it the first month of the year.

Tell the whole community of Israel.

On the tenth of this month, every one of your families must procure for itself a lamb,

one apiece for each household.

If a family is too small for a whole lamb,

it shall join the nearest household in procuring one,

and shall share in the lamb,

in proportion to the number of persons who partake it.

The lamb must be a year old, male, and without blemish.

You may take it from either the sheep or the goats.

You shall keep it until the 14th day of this month,

and then, with the whole assembly of Israel present,

it shall be slaughtered during the evening twilight.

They shall take some of its blood and apply it to the two doorposts and the lentil,

of every house in which they partake of the lamb.
