Ioseph in Prisan, to Pharaoh's Butler at liberty

Whilst we in Prison fettered lay
Our loves were fast, and thou didst say,
Thou surely wouldst (if ever grac't
Againe) relieve me: but thou hast
Let slip thy promise, and my paine,
Though Pharaoh's Cuppe thou holdst againe.
Thus Royall favours Sunne-shine makes
(In Dunghill mindes) ungratefull snakes
Of Libertines, in office set;
And cuppes make men their friends forget.
