Génesis 38

Ma Onan, sapendo che quella progenie non sarebbe sua, quando entrava dalla moglie del suo fratello, si corrompeva in terra, per non dar progenie al suo fratello.

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.
