Read it through once

PROSPERO. Then, as my gift and thine own acquisition Worthily purchas’d, take my daughter: but If thou dost break her virgin knot before All sanctimonious ceremonies may With full and holy rite be minister’d, No sweet aspersion shall the heavens let fall To make this contract grow; but barren hate, Sour-ey’d disdain, and discord shall bestrew The union of your bed with weeds so loathly That you shall hate it both: therefore take heed, As Hymen’s lamps shall light you.
