Gn 38:7-10 (King James)

⁷ And Er, Judah's firstborn, was wicked in the sight of the LORD; and the LORD slew him. 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.

Gn 38:7-10 (Vulgate)

   ⁷ Fuit quoque Her primogenitus Judæ nequam in conspectu Domini : et ab eo occisus est.
   ⁸ Dixit ergo Judas ad Onan filium suum : Ingredere ad uxorem fratris tui, et sociare illi, ut suscites semen fratri tuo.
   ⁹ Ille sciens non sibi nasci filios, introiens ad uxorem fratris sui, semen fundebat in terram, ne liberi fratris nomine nascerentur.
   ¹⁰ Et idcirco percussit eum Dominus, quod rem detestabilem faceret.
