Upon him, as he slept. So as a tree Whose root is by the river's brink, he grew And flourish'd, while the dews like balm-drops hung All night upon his branches. Yet let none Of woman born, presume to build his hopes On the worn cliff of brief prosperity, Or from the present promise, predicate The future joy. The exulting bird that sings Mid the green curtains of its leafy nest His tuneful trust untroubled there to live, And there to die, may meet the archer's shaft When next it spreads the wing. The tempest folds O'er the smooth forehead of the summer noon Its undiscover'd purpose, to emerge Resistless from its armory, and whelm In floods of ruin, ere the day decline. Lightning and sword!
