MARRIAGE, Levirate (the brother required to marry a brother's widow)

Genesis 38:8-11

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

9. And Onan knew that the seed should not be his; and it came to pass, when he went in unto his brother's wife, that he spilled it on the ground, lest that he should give seed to his brother.

10. And the thing which he did displeased the LORD: wherefore he slew him also.

11. 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.

Deuteronomy 25:5-10

5. 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.

6. And it shall be, that the firstborn which she beareth shall succeed in the name of his brother which is dead, that his name be not put out of Israel.

7. And if the man like not to take his brother's wife, then let his brother's wife go up to the gate unto the elders, and say, My husband's brother refuseth to raise up unto his brother a name in Israel, he will not perform the duty of my husband's brother.

8. Then the elders of his city shall call him, and speak unto him: and if he stand to it, and say, I like not to take her;

9. Then shall his brother's wife come unto him in the presence of the elders, and loose his shoe from off his foot, and spit in his face, and shall answer and say, So shall it be done unto that man that will not build up his brother's house.

10. And his name shall be called in Israel, The house of him that hath his shoe loosed.

Ruth 4:5

5. Then said Boaz, What day thou buyest the field of the hand of Naomi, thou must buy it also of Ruth the Moabitess, the wife of the dead, to raise up the name of the dead upon his inheritance.

Matthew 22:24

24. Saying, Master, Moses said, If a man die, having no children, his brother shall marry his wife, and raise up seed unto his brother.

Mark 12:19-23

19. Master, Moses wrote unto us, If a man's brother die, and leave his wife behind him, and leave no children, that his brother should take his wife, and raise up seed unto his brother.

20. Now there were seven brethren: and the first took a wife, and dying left no seed.

21. And the second took her, and died, neither left he any seed: and the third likewise.

22. And the seven had her, and left no seed: last of all the woman died also.

23. In the resurrection therefore, when they shall rise, whose wife shall she be of them? for the seven had her to wife.
