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. Where, Lord? - In what place shall all these dreadful evils fall? The answer our Lord gives in a figure, the application of which they are to make themselves. Where the dead carcass is, there will be the birds of prey - where the sin is, there will the punishment be. See on Matthew 24:28 (note).
Thither will the eagles (or vultures) be gathered together. The jackal or chakal is a devourer of dead bodies; and the vulture is not less so: it is very remarkable how suddenly these birds appear after the death of an animal in the open field, though a single one may not have been seen on the spot for a long period before. The following chapter seems to be a continuation of this discourse: at least it is likely they were spoken on the same occasion. Both contain truths which the reader should carefully ponder, and receive in the spirit of prayer and faith, that he may not come into the same condemnation into which these have fallen.
