TSK · Ruth 4:5

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 now it is true that I am a near kinsman; howbeit there is a kinsman nearer than I.

saying, Teacher, Moses said, If a man die, having no children, his brother shall marry his wife, and raise up seed unto his brother.
