And Judah said unto Onan, Go
in unto thy brother's wife, and marry her, and raise up seed to thy brother.
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.
And if any man's seed of
copulation go out from him, then he shall wash all his flesh in water, and
be unclean until the even. And every garment, and every skin, whereon is the
seed of copulation, shall be washed with water, and be unclean until the
even. The woman also with whom man shall lie with seed of copulation, they
shall both bathe themselves in water, and be unclean until the even.
