NASB
"Onan knew that the offspring would not be his; so when he went in to his brother's wife, he wasted his seed on the ground in order not to give offspring to his brother."
— Genesis 38:9, NASB
“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.”
“And Onan knew that the seed would 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 he should give seed to his brother. ”
“Onan knew that the seed wouldn't be his; and it happened, when he went in to his brother's wife, that he spilled it on the ground, lest he should give seed to his brother.”
“But Onan knew that the child would not be considered his. So whenever he slept with his brother’s wife, he wasted his emission on the ground so as not to give his brother a descendant.”
“He knowing that the children should not be his, when he went in to his brother's wife, he spilled his seed upon the ground, lest children should be born in his brother's name.”
“But Onan, seeing that the offspring would not be his, went in to his brother's wife, but let his seed go on to the earth, so that he might not get offspring for his 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, lest that he should give seed to his brother.”
Now Judah took a wife for Er his firstborn, and her name was Tamar.
But Er, Judah's firstborn, was evil in the sight of the LORD, so the LORD took his life.
Then Judah said to Onan, "Go in to your brother's wife, and perform your duty as a brother-in-law to her, and raise up offspring for your brother."
Onan knew that the offspring would not be his; so when he went in to his brother's wife, he wasted his seed on the ground in order not to give offspring to his brother.
But what he did was displeasing in the sight of the LORD; so He took his life also.
Then Judah said to his daughter-in-law Tamar, "Remain a widow in your father's house until my son Shelah grows up"; for he thought, "I am afraid that he too may die like his brothers." So Tamar went and lived in her father's house.
Now after a considerable time Shua's daughter, the wife of Judah, died; and when the time of mourning was ended, Judah went up to his sheepshearers at Timnah, he and his friend Hirah the Adullamite.
