What does Ezekiel 4:14 mean?

Then said I, Ah Lord Jehovah! behold, my soul hath not been polluted; for from my youth up even till now have I not eaten of that which dieth of itself, or is torn of beasts; neither came there abominable flesh into my mouth.

Then said I, Ah Lord God! behold, my soul hath not been polluted: for from my youth up even till now have I not eaten of that which dieth of itself, or is torn in pieces; neither came there abominable flesh into my mouth.

Then said I, Ah Lord Jehovah! behold, my soul hath not been polluted; for from my youth up even till now have I not eaten of that which dieth of itself, or is torn of beasts; neither came there abominable flesh into my mouth.

Then I said, Ah, Lord! see, my soul has never been unclean, and I have never taken as my food anything which has come to a natural death or has been broken by beasts, from the time when I was young even till now; no disgusting flesh has ever come into my mouth.

And I say, `Ah, Lord Jehovah, lo, my soul is not defiled, and carcase, and torn thing, I have not eaten from my youth, even till now; nor come into my mouth hath abominable flesh.'

And I said: Ah, ah, ah, O Lord God, behold my soul hath not been defiled, and from my infancy even till now, I have not eaten any thing that died of itself, or was torn by beasts, and no unclean flesh hath entered into my mouth.

Then said I, Ah, Lord Jehovah! behold, my soul hath not been defiled, and from my youth up even until now have I not eaten of that which dieth of itself, or of that which is torn; neither came there abominable flesh into my mouth.
