Luke 20:30 Meaning

28Saying, Master, Moses wrote unto us, If any man's brother die, having a wife, and he die without children, that his brother should take his wife, and raise up seed unto his brother.

29There were therefore seven brethren: and the first took a wife, and died without children.

30And the second took her to wife, and he died childless.

31And the third took her; and in like manner the seven also: and they left no children, and died.

32Last of all the woman died also.
