Here's the most beautiful one from the old church in Jeff, Kentucky, then (in my youth) known as The Little Zion Church; it was our dismissal hymn...wish I could give the tune- if anyone wants it, I'll look for help:

Jesus grant us all a blessing,
Send it down, Lord, from above;
May we all go home a-praying
As we try to teach thy love.
Farewell brethern, farewell sisters
Till we all shall meet again.
