C. F. Keil and Franz Delitzsch on Genesis 38:19-21

Gen 38:19-21

After this had occurred, Thamar laid aside her veil, put on her widow’s dress again, and returned home. When Judah, therefore, sent the kid by his friend Hirah to the supposed harlot for the purpose of redeeming his pledges, he could not find her, and was told, on inquiring of the inhabitants of Enayim, that there was no קדשׁה there. הקּדשׁה: lit., “the consecrated,” i.e., the hierodule, a woman sacred to Astarte, a goddess of the Canaanites, the deification of the generative and productive principle of nature; one who served this goddess by prostitution (vid., Deu 23:18). This was no doubt regarded as the most respectable designation for public prostitutes in Canaan.
