Answer:
In the evening I'm long, in the morning I'm smallΝΎ When seen in a ballroom, I'm nothing at all.
What goes through the door without pinching itself? What sits on the stove without burning itself? What sits on the table and is not ashamed?
Two bodies have I, though both joined in one. The more still I stand, the quicker I run.
What goes in, but never through? I've got some and so do you. We might lend one, or even two, but only if our trust is true.
My first is in wield, sever bones and marrow. My second is in blade, forged in cold steel. My third is in arbalest, and also in arrows. My fourth is in power, plunged through a shield. My fifth is in honor, and also in vows My last will put an end to it all.
My days are numbered. What am I?
