Thou! why, thou wilt quarrel with a man that hath a hair more or a hair less in his beard than thou hast. Thou wilt quarrel with a man for cracking nuts, having no other reason but because thou hast hazel eyes.... Thy head is full of quarrels as an egg is full of meat. Rom. and Jul., iii. 1.
Thou wilt never sell thy life, or any part of thy life, in a satisfactory manner. Give it like a royal heart; let the price of it be nothing; then hast thou in a certain sense got all for it. Carlyle.
Thou would'st as soon go kindle fire with snow, / As seek to quench the fire of love with words. Two Gent. of Verona, ii. 7.
Thou wouldst do little for God if the devil 5 were dead. Sc. Pr.
Though a man may become learned by another's learning, he never can be wise but by his own wisdom. (?)
Though a sinner do evil an hundred times, and his days be prolonged, yet surely I know that it shall be well with them that fear God, which fear before him. Bible.
