Matthew 22:23-26

That same day the Sadducees, who say there is no resurrection, came to him with a question. “Teacher,” they said, “Moses told us that if a man dies without having children, his brother must marry the widow and raise up offspring for him. Now there were seven brothers among us. The first one married and died, and since he had no children, he left his wife to his brother. The same thing happened to the second and third brother, right on down to the seventh.
