Read it through once

My mistress bent that brow of hers; Those deep dark eyes where pride demurs When pity would be softening through, Fixed me a breathing-while or two With life or death in the balance: right! The blood replenished me again; My last thought was at least not vain: I and my mistress, side by side, Shall be together, breathe and ride, So, one day more am I deified. Who knows but the world may end to-night?
