'Shearers' in the Bible

Should I take my bread and my water and my meat that I have slaughtered for my shearers and give them to these men? I don't even know where they came from!"

Then Absalom went to the king and said, "My shearers have begun their work. Let the king and his servants go with me."

He was treated harshly and afflicted, but he did not even open his mouth. Like a lamb led to the slaughtering block, like a sheep silent before her shearers, he did not even open his mouth.
