You shall celebrate the Feast of Weeks, that is, the first fruits of the wheat harvest, and the Feast of Ingathering at the turn of the year.
“Three times in a year all your males shall appear before the Lord your God in the place which He chooses, at the Feast of Unleavened Bread and at the Feast of Weeks and at the Feast of Booths, and they shall not appear before the Lord empty-handed. Every man shall give as he is able, according to the blessing of the Lord your God which He has given you.
2 Chronicles 8:13
and did so according to the daily rule, offering them up according to the commandment of Moses, for the sabbaths, the new moons and the three annual feasts—the Feast of Unleavened Bread, the Feast of Weeks and the Feast of Booths.
Also, you shall observe the Feast of the Harvest of the first fruits of your labors from what you sow in the field; also, the Feast of the Ingathering at the end of the year when you gather in the fruit of your labors from the field.
‘You shall also count for yourselves from the day after the sabbath, from the day when you brought in the sheaf of the wave offering; there shall be seven complete sabbaths. You shall count fifty days to the day after the seventh sabbath; then you shall present a new grain offering to the Lord. You shall bring in from your dwelling places two loaves of bread for a wave offering, made of two-tenths of an ephah; they shall be of a fine flour, baked with leaven as first fruits to the Lord.
‘Also, on the day of the first fruits, when you present a new grain offering to the Lord in your Feast of Weeks, you shall have a holy convocation; you shall do no laborious work. You shall offer a burnt offering for a soothing aroma to the Lord: two young bulls, one ram, seven male lambs one year old; and their grain offering, fine flour mixed with oil: three-tenths of an ephah for each bull, two-tenths for the one ram.

“Let us now fear the Lord our God,
Who gives rain in its season,
Both the autumn rain and the spring rain,
Who keeps for us
The appointed weeks of the harvest.”
You shall remember that you were a slave in Egypt, and you shall be careful to observe these statutes.
For Paul had decided to sail past Ephesus so that he would not have to spend time in Asia; for he was hurrying to be in Jerusalem, if possible, on the day of Pentecost.
1 Corinthians 16:8
But I will remain in Ephesus until Pentecost;
When the day of Pentecost had come, they were all together in one place. And suddenly there came from heaven a noise like a violent rushing wind, and it filled the whole house where they were sitting. And there appeared to them tongues as of fire distributing themselves, and they rested on each one of them.
And as I began to speak, the Holy Spirit fell upon them just as He did upon us at the beginning.
“It will come about after this
That I will pour out My Spirit on all mankind;
And your sons and daughters will prophesy,
Your old men will dream dreams,
Your young men will see visions.
“Even on the male and female servants
I will pour out My Spirit in those days. “I will display wonders in the sky and on the earth,
Blood, fire and columns of smoke.
“The sun will be turned into darkness
And the moon into blood
Before the great and awesome day of the Lord comes.
“And it will come about that whoever calls on the name of the Lord
Will be delivered;
For on Mount Zion and in Jerusalem
There will be those who escape,
As the Lord has said,
Even among the survivors whom the Lord calls.
