'Shearers' in the Bible

Now I have heard that you have shearers. Your shepherds have now been with us, and we did them no hurt, neither was there anything missing to them, all the while they were in Carmel.

Shall I then take my bread, and my water, and my meat that I have killed for my shearers, and give it to men who I don't know where they come from?"

He was oppressed, yet when he was afflicted he didn't open his mouth. As a lamb that is led to the slaughter, and as a sheep that before its shearers is mute, so he didn't open his mouth.
