Judah got his daughter-in-law pregnant accidentally. He’s the father of one of the 12 tribes of Israel. But he became the father of twins because he didn’t recognize his daughter-in-law. “He thought she was a prostitute” (Genesis 38:15). She hid her face with a veil. A Visual Walk Through Genesis, page 150.
So strange that he even considered this a valid excuse!
It was a man’s world. What man in the Bible turned down his wife’s offer for a concubine for him to impregnate? None that I know of.
