Ezekiel 24:24

Thus Ezekiel is unto you a sign
These are the words of the prophet concerning himself; observing that in all the above things he was a sign to the Jews of what should befall them, and what should be their case: and according to all that he hath done shall ye do;
however it might be then a matter of scorn and derision: and when this cometh:
when this prophecy comes to pass, and all these calamities come upon the city and temple: ye shall know that I am the Lord God;
omniscient, omnipotent, true, and faithful.
