'Shearers' in the Bible

Some years later, Shua's daughter (that is, Judah's wife) died. As Judah was grieving, he visited the shearers of his flock in Timnah, accompanied by his Adullamite friend Hirah.

Should I take my food, my water, and my meat that I've slaughtered for my shearers and give it to men who came from who knows where?"

He was oppressed and he was afflicted, yet he didn't open his mouth; like a lamb that is led to the slaughter, as a sheep that before its shearers is silent, so he did not open his mouth.
