Genesis 38:23

And Judah said, Let her take it to her, lest we be shamed: behold, I sent this kid, and thou hast not found her.

Judah chose to abandon the effort to recover what he had left with Tamar and to allow her to retain the pledge in her possession. He concluded that he had fulfilled his part by sending the young goat he had promised as payment. Since the woman could not be located despite the search, further inquiry would only expose him to public disgrace. To avoid that shame, he determined that the matter should be dropped rather than pursued further.
