Lk 17, Verses 34–37English original
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.
(de Con. Ev. l. ii. c. 7.) these things which Luke has given us in a different place from Matthew, he either relates by anticipation, so as to mention beforehand what was afterwards spoken by our Lord, or he means us to understand that they were twice uttered by Him.
