Tamar sent the staff, seal, and cord to Judah with a message declaring that the owner of these items was the man who had made her pregnant.
[11] John Emerton regards the connections as evidence for including chapter 38 in the J corpus, and suggests that the J writer dovetailed the Joseph and Judah traditions.

As a judge, Judah gave a decision that Tamar was liable to the death penalty by burning according to the law, for she was the daughter of the high priest (Shem) who was accused of leading an unchaste demeanor.
After Tamar showed the three pledges from the man who came to her, Judah's countenance grew pale to green color when he publicly confessed his relationship with her.
