American Standard Version (ASV):
And 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 have not love, I am nothing.
King James Version (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.
