민수기 26:19의 타나크

Yehudah took a wife for Er, his firstborn, and her name was Tamar.

Er, Yehudah’s firstborn was wicked in the eyes of Adonoy, and Adonoy put him to death.

Yehudah said to Onan, Consummate marriage with your brother’s wife, and fulfill the yibum rite with her, and establish seed for your brother.
