What does Deuteronomy 20:6 mean?

And what man is there that hath planted a vineyard, and hath not used the fruit thereof? let him go and return unto his house, lest he die in the battle, and another man use the fruit thereof.

And what man is he that hath planted a vineyard, and hath not yet eaten of it? let him also go and return unto his house, lest he die in the battle, and another man eat of it.

And what man is there that hath planted a vineyard, and hath not used the fruit thereof? let him go and return unto his house, lest he die in the battle, and another man use the fruit thereof.

Or if any man has made a vine-garden without taking the first-fruits of it, let him go back to his house, so that in the event of his death in the fight, another may not be the first to make use of the fruit.

`And who <FI>is<Fi> the man that hath planted a vineyard, and hath not made it common? --let him go and turn back to his house, lest he die in battle, and another man make it common.

What man is there, that hath planted a vineyard, and hath not as yet made it to be common, whereof all men may eat? let him go, and return to his house, lest he die in the battle, and another man execute his office.

And what man is there that hath planted a vineyard, and hath not eaten of it? let him go and return unto his house, lest he die in the battle, and another man eat of it.
