Where it appears

Appears 3 times in the Bible.

• Genesis 38:17 “I’ll send you a young goat from my flock,” Judah promised. “But what will you give me to guarantee that you will send the goat?” she asked.
• Genesis 38:18 “What kind of guarantee do you want?” he replied. She answered, “Leave me your identification seal and its cord and the walking stick you are carrying.” So Judah gave them to her. Then he had intercourse with her, and she became pregnant.
