NASB: But if anyone says to you, "This is meat sacrificed to idols," do not eat it, for the sake of the one who informed you, and for conscience' sake;
KJV: And though I have the gift of prophecy, and understand all mysteries, and all knowledge; and though I have all faith, so that I could remove mountains, and have not charity, I am nothing.
NASB: If I have the gift of prophecy, and know all mysteries and all knowledge; and if I have all faith, so as to remove mountains, but do not have love, I am nothing.
