'Adullamite' in the Bible

It happened at that time, that Judah went down from his brothers, and visited a certain Adullamite, whose name was Hirah.

After many days, Shua's daughter, the wife of Judah, died. Judah was comforted, and went up to his sheepshearers to Timnah, he and his friend Hirah, the Adullamite.

Judah sent the young goat by the hand of his friend, the Adullamite, to receive the pledge from the woman's hand, but he didn't find her.
