What does Genesis 38:24 mean?

About three months later, someone told Judah, 'Your daughter-in-law Tamar has been acting like a prostitute, and now she’s pregnant.' Judah said, 'Bring her out and burn her.' Genesis 38:24 - Modern Text Bible

(Judah hears Tamar is pregnant and assumes the worst, reacting harshly and hypocritically.)
