6. Afterward Rebbe, Melech HaMoshiach was seen by over five hundred Achim b'Moshiach at one time, of whom most remain alive until now, though some sleep the sleep of the mesim.
7. Afterward, Rebbe, Melech HaMoshiach was seen by Ya'akov (Ga 1:19, also see p.848), then by all the Shlichim.
8. And, last of all, even as if to one born not normally [like the rest], Rebbe, Melech HaMoshiach was seen by me also (cf. 9:1).
9. For I am the least of Moshiach's Shlichim, not qualified to be called a Shliach, because I brought redifah (persecution) upon the Kehillah of Hashem.
10. But by the Chen v'Chesed Hashem I am what I am. And the Chen v'Chesed Hashem of Rebbe, Melech HaMoshiach to me was not in vain, but more abundantly than all the Moshiach's Shlichim I labored, yet it was not I, but the Chen v'Chesed Hashem with me.
11. Whether it was I or those others, so we preached as Moshiach's maggidim, and so you had emunah and became Moshiach's ma'aminim.
12. 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?
13. And if there is no Techiyas HaMesim, neither then has Rebbe, Melech HaMoshiach been raised.
14. And if Rebbe, Melech HaMoshiach has not been raised, then our preaching to you was in vain and also in vain is your emunah (faith).
15. Moreover, we are found also to be edei sheker (false witnesses) [SHEMOT 20:16; DEVARIM 19:16-21] misrepresenting Hashem Himself, because we gave solemn edut (testimony 1:6) 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.
16. For if the Mesim (Dead persons) have not Techiyah, neither has Rebbe, Melech HaMoshiach had a Techiyah;
17. 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),
18. And even the ones who sleep the sleep of the Mesim in Rebbe, Melech HaMoshiach have perished.
19. Listen, if for the Olam Hazeh only we have tikvateinu in Rebbe, Melech HaMoshiach, we are to be pitied more than kol Bnei Adam.
20. But in fact Rebbe, Melech HaMoshiach has had His Techiyah! Rebbe, Melech HaMoshiach is the Bikkurim ("Firstfruits" Gn 1:11-13; Ex 23:16; Lev 23:10-11), the Firstfruits of the ones having fallen asleep [in Moshiach].
21. For als (since) through an Adam (Man) came mavet (Gn 2:17), also through an Adam (Man, Moshiach) came the Techiyas HaMesim.
