'Adullamite' in the Bible

Now at that time, Judah left his brothers and went down to [stay with] a certain Adullamite named Hirah.

But quite a while later, Judah’s wife, the daughter of Shua, died; and when the time of mourning was ended, he went up to his sheepshearers at Timnah with his friend Hirah the Adullamite.

When Judah sent the young goat by his friend the Adullamite, to get his pledge [back] from the woman, he was unable to find her.
