'Adullamite' in the Bible

Right about then, Judah left his brothers and went to live with an Adullamite man named Hirah.

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.

Later on, Judah sent his Adullamite friend to take her a young goat, intending to retrieve what he had put up as security from the woman, but he could not find her.
