of his command.
_You shall_ go home.
_It shall_ not happen again, I promise you.

66. SHALL AND WILL IN QUESTIONS. In interrogative sentences _shall_
should always be used with the first person. In the second and third
persons that auxiliary should be used which is logically expected
in the answer.

Examine the agreement in the use of _shall_ and _will_ in the following
questions and answers:

QUESTIONS. ANSWERS.
_Shall_ I miss the car? You _will_ miss it.
_Shall_ you be there? I think I _shall_ (probability).
_Will_ he do it? I think he _will_ (assertion).
_Shall_ your son obey the teacher? He _shall_ (determination).
_Will_ you promise to come? We _will_ come (promise).

67. SHALL AND WILL IN DEPENDENT CLAUSES. In dependent clauses which
are introduced by _that_, expressed or understood, the auxiliary
should be used which would be proper if the dependent clause were
a principal clause. The sentence, _They assure us that they SHALL
come_, is wrong. The direct assurance would be, _We WILL come_.
The auxiliary, then, in a principal clause would be _will_. _Will_
should, therefore, be the auxiliary in the dependent construction,
and the sentence should read, _They assure us that they WILL come_.
Further examples:

I suppose _we shall_ have to pay.
He thinks that _you will_ be able to do it.
He has decided that _John shall_ replace the book.

In all dependent clauses expressing a condition or contingency use
_shall_ with all subjects. Examples;

_If he shall_ go to Europe, it will be his tenth trip abroad.
_If you shall_ go away, who will run the farm?
_If I shall_ die, I shall die as an honest man.
