John ( Gv 20,19-23 in Italian is therefore read.
Jesus comes to into a closed house in Jerusalem that hosted the Apostles and other followers of Jesus. They were in Jerusalem celebrating the Feast of Weeks Shavuot, as described in the Acts of the Apostles (Acts 2:1–31)
Yo understand the message i think it is important to know what Pentecost and most important of all, what Shavout really is.
The term Pentecost comes from the Greek Πεντηκοστή (Pentēkostē) meaning “fiftieth”. It refers to the festival celebrated on the fiftieth day after Passover, also known as the “Feast of Weeks” and the “Feast of 50 days” in rabbinic tradition.
The Septuagint uses the term Pentēkostē to refer to the “Feast of Pentecost” only twice, in the deuterocanonical Book of Tobit and 2 Maccabees. The Septuagint writers also used the word in two other senses: to signify the year of Jubilee (Leviticus 25:10), an event which occurs every 50th year, and in several passages of chronology as an ordinal number.[ii] The term has also been used in the literature of Hellenistic Judaism by Philo of Alexandria and Josephus ( Read more in Wiki )
I paste here the text in Wikipedia as I think it gives the information needed.
“Shavuot (listen (help·info)), Yiddish Shovues (listen (help·info)) in Ashkenazi usage, (Hebrew: שָׁבוּעוֹת, lit. “Weeks”), is known as the Feast of Weeks or Pentecost (Koinē Greek: Πεντηκοστή) in English. It is a Jewish holiday that occurs on the sixth day of the Hebrew month of Sivan (it may fall between May 15 and June 14 on the Gregorian calendar).[Note 1]
Shavuot has a double significance, agricultural and spiritual. Agriculturally it marks the all-important wheat harvest in the Land of Israel (Exodus 34:22), and spiritually it commemorates the anniversary of the day when God gave the Torah to the nation of Israel assembled at Mount Sinai—although the association is not explicit in the Biblical text between the giving of the Torah (Matan Torah) and Shavuot.
The holiday is one of the Three Pilgrimage Festivals of the Bible. The word Shavuot means “weeks” and it marks the conclusion of the Counting of the Omer. Its date is directly linked to that of Passover; the Torah mandates the seven-week Counting of the Omer, beginning on the second day of Passover, to be immediately followed by Shavuot. This counting of days and weeks is understood to express anticipation and desire for the giving of the Torah. On Passover, the people of Israel were freed from their enslavement to Pharaoh; on Shavuot, they were given the Torah and became a nation committed to serving God. The yahrzeit of King David is traditionally observed on Shavuot. Hasidic Jews also observe the yahrzeit of the Baal Shem Tov.
Shavuot is celebrated in Israel by all congregations for one day including Conservative and Orthodox. As with other biblical holidays however Shavuot is celebrated by Conservative and Orthodox congregations in the Diaspora for two days (Yom tov sheni shel galuyot), however Reform congregations celebrate for a single day regardless of location.“
