Hirah the Adullamite

Later Judah asked his friend Hirah the Adullamite to take the young goat to the woman and to pick up the things he had given her as his guarantee. But Hirah couldn't find her. So he asked the men who lived there, "Where can I find the shrine prostitute who was sitting beside the road at the entrance to Enaim?"
"We've never had a shrine prostitute here," they replied.
So Hirah returned to Judah and told him, "I couldn't find her anywhere, and the men of the village claim they've never had a shrine prostitute there."
"Then let her keep the things I gave her," Judah said. "I sent the young goat as we agreed, but you couldn't find her. We'd be the laughingstock of the village if we went back again to look for her." (Genesis 38:20-23 NLT)

We have brothers and we also have friends. Sometimes we share things with our friends that we do not share with brothers.

Judah had a friend named Hirah the Adullamite. After Judah went into what he thought was a prostitute, he got his friend Hirah the Adullamite to help him to send the payment.

About three months later, Judah was told, "Tamar, your daughter-in-law, has acted like a prostitute. And now, because of this, she's pregnant."
"Bring her out, and let her be burned!" Judah demanded.
But as they were taking her out to kill her, she sent this message to her father-in-law: "The man who owns these things made me pregnant. Look closely. Whose seal and cord and walking stick are these?"
Judah recognized them immediately and said, "She is more righteous than I am, because I didn't arrange for her to marry my son Shelah." And Judah never slept with Tamar again.
When the time came for Tamar to give birth, it was discovered that she was carrying twins. While she was in labor, one of the babies reached out his hand. The midwife grabbed it and tied a scarlet string around the child's wrist, announcing, "This one came out first." But then he pulled back his hand, and out came his brother! "What!" the midwife exclaimed. "How did you break out first?" So he was named Perez. Then the baby with the scarlet string on his wrist was born, and he was named Zerah. (Genesis 38:24-30 NLT)

Judah was the father of Perez and Zerah (whose mother was Tamar). Perez was the father of Hezron. Hezron was the father of Ram. (Matthew 1:3 NLT)
