Genesis 38:8

King James 2000

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

See the chapter Copy

And the firstborn said unto the younger, Our father is old, and there is not a man on the earth to come in unto us after the manner of all the earth:

You shall not uncover the nakedness of your brother's wife: it is your brother's nakedness.

And Naomi said, Turn again, my daughters: why will you go with me? are there yet any more sons in my womb, that they may be your husbands?
