Recorded in both Matthew 24:15-28 and Luke 17:22-37, the parable following a description given by Jesus of His second coming. When and where that is to happen He refuses to tell His disciples, but He assures them, that when it does happen it will be so evident that they will realize it of themselves, just as the eagles find by instinct and with their senses a carcass without further indication. Hence, there is no need to fear deception by false prophets, announcing the second coming of Christ; the very fact that this so-called Christ needs announcing is proof that he is not the true Christ. Let, them therefore live in peaceful preparation until they actually find themselves before their Lord and Master.
– Luke 17:22-37, Revised Standard Version
“So when you see the desolating sacrilege spoken of by the prophet Daniel, standing in the holy place (let the reader understand), then let those who are in Judea flee to the mountains; let him who is on the housetop not go down to take what is in his house; and let him who is in the field not turn back to take his mantle. And alas for those who are with child and for those who give suck in those days! Pray that your flight may not be in winter or on a sabbath. For then there will be great tribulation, such as has not been from the beginning of the world until now, no, and never will be. And if those days had not been shortened, no human being would be saved; but for the sake of the elect those days will be shortened. Then if any one says to you, `Lo, here is the Christ!’ or `There he is!’ do not believe it. For false Christs and false prophets will arise and show great signs and wonders, so as to lead astray, if possible, even the elect. Lo, I have told you beforehand. So, if they say to you, `Lo, he is in the wilderness,’ do not go out; if they say, `Lo, he is in the inner rooms,’ do not believe it. For as the lightning comes from the east and shines as far as the west, so will be the coming of the Son of man. Wherever the body is, there the eagles will be gathered together.
