What does 1 Samuel 21:5 mean?

And David answered the priest, and said unto him, Of a truth women have been kept from us about these three days; when I came out, the vessels of the young men were holy, though it was but a common journey; how much more then to-day shall their vessels be holy?

And David answered the priest, and said unto him, Of a truth women have been kept from us about these three days, since I came out, and the vessels of the young men are holy, and the bread is in a manner common, yea, though it were sanctified this day in the vessel.

And David answered the priest, and said unto him, Of a truth women have been kept from us about these three days; when I came out, the vessels of the young men were holy, though it was but a common journey; how much more then to-day shall their vessels be holy?

And David in answer said to the priest, Certainly women have been kept from us; and as has been done before when I have gone out the arms of the young men were made holy, even though it was a common journey; how much more today will their arms be made holy.

And David answereth the priest, and saith to him, `Surely, if women have been restrained from us as heretofore in my going out, then the vessels of the young men are holy, and it <FI>is<Fi> a common way: and also, surely to-day it is sanctified in the vessel.'

And David answered the priest, and said to him: Truly, as to what concerneth women, we have refrained ourselves from yesterday and the day before, when we came out, and the vessels of the young men were holy. Now this way is defiled, but it shall also be sanctified this day in the vessels.

And David answered the priest and said to him, Yes indeed, women have been kept from us about these three days, since I came out, and the vessels of the young men are holy, and the [bread] is in a manner common, and the more so, because to-day [new] is hallowed in the vessels.
