Mark 12:19-23
19 “Teacher,” they said, “Moses wrote for us that if a man’s brother dies and leaves a wife but no children, the man must marry the widow and have children for his brother. 20 Now there were seven brothers. The first one married and died without leaving any children. 21 The second one married the widow, but he also died, leaving no child. It was the same with the third. 22 In fact, none of the seven left any children. Last of all, the woman died too. 23 At the resurrection whose wife will she be, since the seven were married to her?”
