In case; if; -- used to introduce the first or two or more alternative clauses, the other or others being connected by or
, or by or whether
. When the second of two alternatives is the simple negative of the first it is sometimes only indicated by the particle not
after the correlative, and sometimes it is omitted entirely as being distinctly implied in the whether
of the first. [1913 Webster
"And now who knows
But you, Lorenzo, whether I am yours?"
"You have said; but whether wisely or no, let the forest judge."
"For whether we live, we live unto the Lord; and whether we die, we die unto the Lord; whether we live therefore, or die, we are the Lord's."
"But whether thus these things, or whether not;
Whether the sun, predominant in heaven,
Rise on the earth, or earth rise on the sun, . . .
Solicit not thy thoughts with matters hid."
