Genesis 38:6-9

6And JudahH3063 tookH3947 a wifeH802 for ErH6147 his firstbornH1060, and her nameH8034 was TamarH8559.

7And ErH6147, Judah's firstbornH1060, wasH1961 wickedH7451 in the sight of Jehovah, and Jehovah slew him.

8Then JudahH3063 saidH559 to OnanH209, GoH935 in to thy brother's wifeH802, and fulfil to her the brother-in-law's duty, and raiseH6965 up seedH2233 to thy brotherH251.

9But when OnanH209 knewH3045 that the seedH2233 should not beH1961 his own, it cameH935 to pass when he wentH935 in to his brother's wifeH802, that he spilled [it] on the groundH776, in order to giveH5414 no seedH2233 to his brotherH251.
