Genesis 38:8

And Judah said unto Onan, Go in unto thy brother's wife, and marry her, and raise up seed to thy brother.

Judah said to Onan, "Go in to your brother's wife, and perform the duty of a husband's brother to her, and raise up seed to your brother."

And Judah said unto Onan, Go in unto thy brother's wife, and perform the duty of a husband's brother unto her, and raise up seed to thy brother.

And Judah saith to Onan, `Go in unto the wife of thy brother, and marry her, and raise up seed to thy brother;'

Then Judah said to Onan, “Sleep with your brother’s wife. Perform your duty as her brother-in-law and raise up offspring for your brother.”
