Contradiction with Genesis 38:24
This verse shows Judah ordering the punishment for Tamar's alleged fornication, contradicting his previous ignorance of her widowhood attire in Genesis 38:13.
Genesis 38:24: And it came to pass about three months after, that it was told Judah, saying, Tamar thy daughter in law hath played the harlot; and also, behold, she [is] with child by whoredom. And Judah said, Bring her forth, and let her be burnt.
