Luke 17:33-37 says,
"Remember Lot's wife. Whosoever shall seek to save his life shall lose it; and whosoever shall lose his life shall preserve it. I tell you, in that night there shall be two men in one bed; the one shall be taken, and the other shall be left. Two women shall be grinding together; the one shall be taken, and the other left. Two men shall be in the field; the one shall be taken, and the other left. And they answered and said unto him, Where, Lord? And he said unto them, Wheresoever the body is, thither will the eagles be gathered together. "Remember Lot's wife.

I tell you, in that night there shall be two men in one bed; the one shall be taken, and the other shall be left. Two women shall be grinding together; the one shall be taken, and the other left.

And he said unto them, Wheresoever the body is, thither will the eagles be gathered together.
In this passage, Jesus is referring to those who would be taken, and those who would be "Left Behind". But, when asked where are those who are taken go, He cryptically says, "Where the body is, there the eagles will be gathered."
My question is, Who are taken, and who are left behind, and how are we to understand Luke 17:37?
