الصفحة 23 - Thyself how wondrous then ! Unspeakable, who sit'st above these Heavens, To us invisible, or dimly seen In these thy lowest works ; yet these declare Thy goodness beyond thought, and power divine.
الصفحة 449 - THERE was an ancient sage philosopher That had read Alexander Ross over, And swore the world, as he could prove, Was made of fighting and of love. Just so Romances are, for what else Is in them all but love and battles ? O' th' first of these w' have no great matter To treat of, but a world o' th' latter, In which to do the injured right We mean, in what concerns just fight.

It can embroider muslin and forge anchors, cut steel into ribbons, and impel loaded vessels against the fury of the winds and waves.
الصفحة 118 - I seen also under the sun, and it seemed great unto me: there was a little city, and few men within it; and there came a great king against it, and besieged it, and built great bulwarks against it: now there was found in it a poor wise man, and he by his wisdom delivered the city; yet no man remembered that same poor man. Then said I, "Wisdom is better than strength: nevertheless the poor man's wisdom is despised, and his words are not heard.
الصفحة 385 - Ye shall do no unrighteousness in judgment, in meteyard, in weight, or in measure. Just balances, just weights, a just ephah, and a just hin, shall ye have : I am the Lord your God, which brought you out of the land of Egypt.
الصفحة 33 - The bell strikes One. We take no note of time But from its loss: to give it then a tongue Is wise in man. As if an angel spoke, I feel the solemn sound. If heard aright, It is the knell of my departed hours. Where are they ? With the years beyond the flood.
