Genesis 38:7-10

LXX2012(i) 7 And Er, the firstborn of Judas, was wicked before the Lord; and God killed him. 8 And Judas said to Aunan, Go in to your brother's wife, and marry her as her brother-in-law, and raise up seed to your brother. 9 And Aunan, knowing that the seed should not be his—it came to pass when he went in to his brother's wife, that he spilled [it] upon the ground, so that he should not give seed to his brother's wife. 10 And his doing this appeared evil before God; and he killed him also.
