They were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance.@Acts 2:4

Rejoice! the year upon its way
Has brought again that blessèd day,
When on the chosen of the Lord
The Holy Spirit was outpoured.

On each the fire, descending, stood
In quivering tongues’ similitude—
Tongues, that their words might ready prove,
And fire, to make them flame with love.

To all in every tongue they spoke;
Amazement in the crowd awoke,
Who mocked, as overcome with wine,
Those who were filled with power divine.

These things were done in type that day,
When Eastertide had passed away,
The number told which once set free
The captive at the jubilee.

And now, O holy God, this day
Regard us as we humbly pray,
And send us, from Thy heavenly seat,
The blessings of the Paraclete.

To God the Father, God, the Son,
And God the Spirit, praise be done;
May Christ the Lord upon us pour
The Spirit’s gift forevermore.
