Judah doesn’t know that god killed his sons.

Genesis 38:11 says, “Then said Judah to Tamar his daughter in law, Remain a widow at thy father's house, till Shelah my son be grown: for he said, Lest peradventure he die also, as his brethren did. And Tamar went and dwelt in her father's house.”   Didn’t Judah know that the god he worshipped killed his sons?  One of them because he knew he shouldn’t get his dead brothers wife pregnant but god obviously wasn’t the one who made him know that because god killed him because of it.  This would make a great season for a soap opera.
