Judah said to Onan, "Sleep with your brother’s wife and fulfill your duty to her as a brother-in-law to raise up offspring for your brother." 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. And the thing which he did displeased the Lord: wherefore he slew him also. (Genesis 38:8-10)
Levirate marriage is an extremely ancient practice in which the widow of the deceased brother marries one of his brothers. Levirate marriage is practiced by societies with a strong clan and caste structures in which exogamous marriage is forbidden. The practice is found among the cattle-herding Nuer and Dinka of the Nile. It also is found among the Igbo of southeastern Nigeria, and in the Punjab-Haryana region of Pakistan, and among early peoples of Central Asia such as the Saka and Kushan.
Now in earlier times in Israel, for the redemption and transfer of property to become final, one party took off his sandal and gave it to the other. This was the method of legalizing transactions in Israel. (Ruth 4:7)
