Here’s what nobody told you: Pentecost has a runway. It’s forty-nine days long, it starts at Passover, and for thousands of years Jewish people have marked every single day of it out loud.
The disciples were doing it the year the Spirit fell. The crowd in Jerusalem knew exactly what day it was when the wind came through. The practice is called the Counting of the Omer, and once you understand it, the whole stretch from resurrection to Acts 2 looks completely different.
So What’s an Omer, Exactly?
An omer is a unit of dry measure, roughly two quarts of grain. Not a mystical concept on its own. Just a quantity.
The reason it matters is what Israel was commanded to do with it.
When the people of God entered the land, the Torah gave this instruction: on the second day of Passover, the 16th of Nisan, the kohen (priest) would wave a sheaf of the firstfruits of the barley harvest before the Lord.
That single omer of barley was the opening movement of a sacred countdown. And from that evening, the counting began.
Here’s the command directly from Leviticus 23:15-16 (TLV):
“Then you are to count from the morrow after the Shabbat, from the day that you brought the omer of the wave offering, seven complete Shabbatot. Until the morrow after the seventh Shabbat you are to count fifty days, and then present a new grain offering to ADONAI.”
Here “Shabbat” refers not to the weekly Sabbath, but to the appointed day of rest during Passover, the first day of Unleavened Bread, which is also called a Shabbat.
Seven complete weeks. Forty-nine days counted aloud, one day at a time. On the fiftieth day: Shavuot.
Deuteronomy says:
“Seven weeks you are to count for yourself — from the time you begin to put the sickle to the standing grain you will begin to count seven weeks. Then you will keep the Feast of Shavuot to ADONAI your God.” (Deuteronomy 16:9-10, TLV)
This Was Never Just About Agriculture
Yes, the Omer period tracks the grain harvest. Barley at the beginning. Wheat at the end. The agricultural rhythm of the land of Israel is literally written into Israel’s liturgical calendar.
But the counting was never only about grain.
The journey from Passover to Shavuot tells the story of Israel’s formation as a people. They left Egypt redeemed by the blood of the lamb, passed through the sea, walked through the wilderness.
At the end of that journey they stood at the foot of Sinai and received the Torah. Jewish tradition holds that the giving of the Torah at Sinai happened in the season of Shavuot… making the Omer period a liturgical re-living of that wilderness walk, from liberation to covenant, from freedom to formation.
Honest caveat worth noting: the Torah tells us the giving of the Torah happened “in the third month” (Exodus 19:1), but Scripture doesn’t explicitly pin the date to the fiftieth day.
The connection between Shavuot and Matan Torah, the giving of the Torah, is deeply embedded in Jewish tradition and it’s a beautiful, compelling, and probable connection… but it belongs in the category of tradition rather than explicit biblical statement.
What Scripture does make plain is that Passover and Shavuot are liturgically tethered. Shavuot is actually the only major Jewish festival in the Torah where no fixed calendar date is given. Its date is entirely determined by the Omer count. You cannot celebrate Shavuot without first counting from Passover. The end of the counting is the feast.
The Practice Itself
In Jewish tradition, the counting is done each evening after nightfall, beginning on the second night of Passover. Each day has its own declaration:
“Today is [X] days of the Omer.”
Traditionally, a blessing is recited before the count:
Baruch atah Adonai Eloheinu Melech ha’olam, asher kid’shanu b’mitzvotav v’tzivanu al sefirat ha’omer.
“Blessed are You, Lord our God, King of the Universe, who has sanctified us with Your commandments and commanded us to count the Omer.”
The count goes forty-nine days, and on day fifty, Shavuot arrives.
And Then Comes Acts 2
This is where the whole thing opens up for followers of Yeshua.
Most people who grew up in the church know the story of Pentecost. Wind, fire, tongues, three thousand people in a single morning. What often goes untaught is that Pentecost didn’t happen in a vacuum. It happened on Shavuot.
The disciples weren’t randomly gathered in Jerusalem. They were there because the Torah commanded the Jewish people to appear before the Lord in Jerusalem three times a year, and Shavuot was one of those pilgrimage feasts. They were Jewish believers observing a commanded feast when the Ruach ha-Kodesh (Holy Spirit) arrived.
“When the day of Shavuot had come, they were all together in one place.” (Acts 2:1, TLV)
Not a vague church holiday disconnected from Torah, but Shavuot, the fiftieth-day feast Israel had been commanded to count toward. The exact feast they’d been counting toward for forty-nine days.
And here’s what that means: the disciples spent a significant portion of the Omer in the company of the risen Yeshua. After His resurrection, He appeared to His disciples for forty days, teaching about the Kingdom of God. Then He ascended. Ten days of waiting. And then the fiftieth day arrived, and the Ruach fell.
Just as Israel walked from Passover redemption to Sinai revelation, the first followers of Yeshua walked from His sacrifice at Passover to the outpouring of the Spirit at Shavuot. Same feast. Same structure. A new and deeper fulfillment.
Should You Count the Omer?
The Counting of the Omer is a command given to Israel in the Torah. It was given in the context of the Levitical priesthood, the land of Israel, the Temple sacrifices, and Israel’s covenant identity as a people. It is not a command issued to Gentile believers, and I’m not going to frame it as one.
What I will say is this: the practice is available to you, and there is something genuinely formative about it.
Forty-nine days of intentional, daily counting. You’re not just crossing off a calendar. You’re rehearsing a journey, orienting yourself each evening to what God accomplished at Passover and what He fulfilled at Shavuot.
You’re participating in a rhythm that the first believers in Yeshua lived inside of, that shaped the way they understood their own history, and that was the very structure of time they were standing in when the Spirit came.
The disciples lived inside that count. They waited within that rhythm. They were all together in one place when the promise arrived.
If you want to join that rhythm, the sheet attached to this post will walk you through it. One day at a time, evening by evening, from the second night of Passover to Shavuot.
How the Counting Works
The counting begins on the evening of the second day of Passover. Each evening after nightfall, you count the day aloud. If you miss an evening, you can catch up the following day, though Jewish tradition holds that the blessing is omitted for any subsequent nights once a day has been missed.
The full count is forty-nine days. Day fifty is Shavuot.
And on Shavuot, it is customary to stay up all night studying Torah and eating lots of dairy (cheesecake is almost expected!) It is also customary to read the Book of Ruth!
I am planning on hosting an all night study where we will study Ruth, study other topics in scripture and you are invited to join me! More details to come! I am also going to see about having additional speakers so I can take breaks! So stay tuned.
If an all night study interests you, let me know in the comments!
A prayer for the counting:
Lord, as I count these days, make me someone who waits well. Teach me to live in the space between what You have already done and what You are still going to do. I count because You are worth counting toward. Amen.
The counting is not magic. The counting is formation. Day by day, you are becoming someone who arrives ready.

Thank you for this!
I've been wanting to start observing Passover and dig deeper into traditional practices around it.
I would be interested in an all-night Bible Study!!
