Henry IV, Part 2
(Auto-generated)

The king that loved him, as the state stood then, Was force perforce compell'd to banish him: And then that Henry Bolingbroke and he, Being mounted and both roused in their seats, Their neighing coursers daring of the spur, Their armed staves in charge, their beavers down, Their eyes of fire sparkling through sights of steel, And the loud trumpet blowing them together, Then, then, when there was nothing could have stay'd My father from the breast of Bolingbroke, O, when the king did throw his warder down, His own life hung upon the staff he threw; Then threw he down himself and all their lives That by indictment and by dint of sword Have since miscarried under Bolingbroke.†
Scene 4.1

Scene 5.5
I like this fair proceeding of the king's: He hath intent his wonted followers Shall all be very well provided for; But all are banish'd till their conversations Appear more wise and modest to the world.†
