'Wool' in the Bible

Now there was a man in Maon whose business was in Carmel; he was a great man and had three thousand sheep and a thousand goats: and he was cutting the wool of his sheep in Carmel.

And David had word in the waste land that Nabal was cutting the wool of his sheep.

I have had word that you have wool-cutters: now the keepers of your sheep have been with us, and we have done them no evil, and taken nothing of theirs while they were in Carmel.

Am I to take my bread and my wine and the meat I have got ready for my wool-cutters and give it to men coming from I have no idea where?
