⁶ Then Judah took a wife for Er, his firstborn, whose name was Tamar.

⁷ Now, Er, the firstborn of Judah, was wicked in the sight of the LORD. Therefore, the LORD killed him.

⁸ And Judah said to Onan, “Go into your brother’s wife and do the office of a kinsman to her; and raise up seed to your brother.”
