This is actually an Israeli song with lovely lyrics (see below) but I think it makes a good Jewish instrumental too.
Reiach TapuachHere’s me singing it while playing very amateurish piano at my wedding song blog: Reiach Tapuach
Translation:
Come back little bird, on the shoulder of the wind…
The fruit is opening up in my garden
The lemon scent lights up the apple
The rain is gone and winter is past.O, who will bring you the letter?
Who will bring a bride to my garden?
I’ll build you a nest of linen on a tree top
Scent of apples and ruby scarlet.Come, please come, gazelle of delight
The fields are dressed in clothes of dew
The sun already reddened for us
And in our glass is red wine.O who will fly, hover in the sky?
Who will bring you the tidings of spring?
Who will bring a bride on wings?
Who will bring you to my garden?Come back, for the winter is over,
Summer brings a new dawn
Return to me, to your nest, little bird,
Come back gazelle to the deer’s cradle.

I play fiddle, concertina, piano, viola, and sometimes viola with two bands in central North Carolina, near RDU and the Research Triangle (actually closer to Chapel Hill and Hillsborough than Durham, but anyway, central). You can see these two wedding ensembles at our site
