'Itself' in the Bible

verily, verily, I say to you, if the grain of the wheat, having fallen to the earth, may not die, itself remaineth alone; and if it may die, it doth bear much fruit;

remain in me, and I in you, as the branch is not able to bear fruit of itself, if it may not remain in the vine, so neither ye, if ye may not remain in me.

And there are also many other things -- as many as Jesus did -- which, if they may be written one by one, not even the world itself I think to have place for the books written. Amen.
