April 17, 2025, Holy Thursday, evening mass of the Lord's Supper.

A reading from the Book of Exodus.

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 10th 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 land in proportion to the number of persons who partake of it.

Holy Thursday.

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 lintel

of every house in which they partake of the lamb.

That same night they shall eat its roasted flesh

with unleavened bread and bitter herbs.

This is how you are to eat it.

With your loins girt, sandals on your feet,

and your staff in hand, you shall eat like those who are in flight. It is the Passover of the Lord. For on this same night I will go through Egypt, striking down every firstborn of the land,
