1 Corinthians 15:12-20

And if Moshiach is being preached that from the Mesim (Dead ones) he has had his Techiyah (Resurrection), how is it that some among you say that there is no Techiyas HaMesim? And if there is no Techiyas HaMesim, neither then has Rebbe, Melech HaMoshiach been raised. And if Rebbe, Melech HaMoshiach has not been raised, then our darshenen to you was in vain and also in vain is your emunah (faith). Moreover, we are found also to be edei sheker (false witnesses) misrepresenting HASHEM Himself, because we gave solemn edut (testimony) as in the presence of G-d that HASHEM raised Rebbe, Melech HaMoshiach — whom, of course, He did not raise if, as you say, the Mesim are not bemetzius (in fact) raised. For if the Mesim (Dead persons) have not Techiyah, neither has Rebbe, Melech HaMoshiach had a Techiyah; And if Rebbe, Melech HaMoshiach has not already had his Techiyah from the Mesim, your emunah is futile, you are still in your averos (sins), And even the ones who sleep the sleep of the Mesim in Rebbe, Melech HaMoshiach have perished. Listen, if for the Olam Hazeh only we have tikvateinu in Rebbe, Melech HaMoshiach, we are to be pitied more than kol Bnei Adam. But in fact Rebbe, Melech HaMoshiach has had His Techiyah! Rebbe, Melech HaMoshiach is the Bikkurim (Firstfruits), the Firstfruits of the ones having fallen asleep [in Moshiach].
