If it is for a service, not a harvest supper, what about Blessed Quietness?:

BLESSED QUIETNESS

Joys are flowing like a river, since the Comforter has come
He abides with us forever, makes the trusting heart his home.

Chorus
Blessed quietness, holy quietness, what assurance in my soul
On the stormy sea, speaking peace to me How the billows cease to roll.

Like the falling rain from Heaven, like the sunlight from the sky
So the Holy Ghost is given, falling on us from on high.

See a fruitful field is growing blessed fruits of righteousness
And the streams of light are flowing in the lonely wilderness

What a wonderful salvation, where we always see His face
What a peaceful habitation, what a quiet resting place.

Joys are flowing like a river, since the Comforter has come
He abides with us forever, makes the trusting heart his home.
