John Gill Commentary Luke 21:8

"And he said, Take heed that ye be not led astray: for many shall come in my name, saying, I am [he]; and, The time is at hand: go ye not after them." — Luke 21:8 (ASV)

And he said, take heed that you be not deceived With false Christs, and false prophets: for many shall come in my name ; making use of his name, taking it to them; not that they would pretend they were sent by him, but that they were he himself: saying, I am [Christ] ; so the Syriac and Persic versions supply as we do: and the time draws near ; not that such will come, but when come, they will say, that the time of the deliverance of the Jewish nation from the Roman yoke is at hand: go you not therefore after them ; do not be their disciples, or follow them where they would lead you; for nothing but destruction will be the consequence of it.
