Leviticus 23:19-21

New Century Version

¹⁹ You must also offer one male goat for a sin offering and two male, one-year-old lambs as a fellowship offering.

²⁰ “‘The priest will present the two lambs as an offering before the Lord, along with the bread from the first wheat of the harvest. They are holy to the Lord, and they will belong to the priest. ²¹ On that same day you will call a holy meeting; you must not do any work that day. This law will continue for you from now on, wherever you live.
