VERBS, AUXILIARY. Be in questions and dependent sentencesBe in questions and dependent sentences. So, as a rule, it will be found that be is used with some notion of doubt, question, thought, &c.; for instance, (a) in questions, and (b) after verbs of thinking. （a)
“Be my horses ready?
This is especially frequent in questions of appeal:
“Be the players ready?
“Where be his quiddities?
“Where be the bending knees that flatter'd thee?
“Where be thy brothers?

“Ford. Well, I hope it be not so.
where, though the latter part is of course fanciful, there is a real fear that the bracelet may be lost. Also, in a dependent sentence like the following:
“I kissed it (the bracelet):

That I kiss aught but he,

“Haply a woman's voice may do some good

it can scarcely be asserted that "for" is "for that" or "because." It is more probable that the scene originally ended there, and that Shakespeare used be in order to get the rhyme, which so often terminates a scene.
