Theophylact of Ohrid
Catena Aurea · Lukasevangelium 17
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.
Or He teaches us the suddenness of Christ’s coming, which we are told will be in the night. And having said that the rich can scarcely be saved, He shews that not all the rich perish, nor all the poor are saved.
