Ruth

If brethren dwell together, and one of them die, and have no child, the wife of the dead shall not marry without unto a stranger: her husband’s brother shall go in unto her, and take her to him to wife, and perform the duty of an husband’s brother unto her.

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.

Then said Jesus unto the twelve, Will ye also go away?

For it is written, Rejoice, thou barren that bearest not; break forth and cry, thou that travailest not: for the desolate hath many more children than she which hath an husband.

And Judah said unto Onan, Go in unto thy brother’s wife, and marry her, and raise up seed to thy brother.
