Book III, 63: On Grapes

It is receiv'd, That seed of Grapes being sowne,
Brings forth degenerate Clusters, or else none:
But Stocks being grafted prove a fruitfull Vine,
Whose pleasing Berries yeeld a generous wine;
We are thy Vineyard, Lord; These Grapes of our,
By Nature, are degenerous and sower;
But if thou please to graft us, we shall beare
Delicious fruit; which being prest, shall cheare
The hearts of Angels, and that blessed Trine
Of perfect glory with their sprightly Wine.
