17 But when I would this thing, whether I used unsteadfastness, either those things that I think, I think after the flesh, that at me be, it is and it is not? [or that there be at me, is and is not, or yea and nay?]

18 But God is true, for our word that was at you, is and is not, is not therein, but is is in it, [or there is not in it yea and nay/there is not in it is and nay, but is, that is truth, is in it].

19 For why Jesus Christ, the Son of God, which is preached among you by us, by me, and Silvanus, and Timothy, there was not in him, is and is not, but is was in him [or there was not in him yea and nay, but is, or yea, was in him/but in him was is].
