divided the shell
two halves; sandy shore and sea
the clam holds a pearl
falling for gems, dive deeply
sup then sell, discard the shell
make ready your home
to keep out the cold brisk dawn
that will fall too soon
her face is your pearl, your heart
you must bind, for wedded bliss
share salt tears of joy
even when her luster fades -
as you both will age

Note: just for fun I went to the Google translator:
from the post:
hamaguri no futami ni wakare yuku aki zo
Through Google translator (the second is this what you mean):
Hama guri no futa mi ni waka re yuku aki zo
Autumn to go is divided into Futami of clam -
My interpretation:
the clam of autumn like Futami is divided
Some, though not all clams have pearls, and the rest... just followed.
