Génesis 38

Onan, sachant que cette postérité ne serait pas à lui, se souillait à terre lorsqu’il allait vers la femme de son frère, afin de ne pas donner de postérité à son frère.

Y sabiendo Onán que la simiente no había de ser suya, sucedía que cuando entraba á la mujer de su hermano vertía en tierra, por no dar simiente á su hermano.

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.

Onan knew that the offspring wouldn’t be his; and when he went in to his brother’s wife, he spilled his semen on the ground, lest he should give offspring to his brother.
