A.) Be this the whetstone of your sword. Let grief / Convert to anger; blunt not the heart, enrage it.
B.) Well, more anon.—Comes the king forth, I pray you?
C.) Good God, betimes remove / The means that makes us strangers!
D.) Be ’t their comfort / We are coming thither.
I think this is either option A, or B. As they sound more as instructions.
