Genesis 38:8

The Message

So Judah told Onan, “Go and sleep with your brother’s widow; it’s the duty of a brother-in-law to keep your brother’s line alive.” But Onan knew that the child wouldn’t be his, so whenever he slept with his brother’s widow he spilled his semen on the ground so he wouldn’t produce a child for his brother. God was much offended by what he did and also took his life.

But Naomi was firm: “Go back, my dear daughters. Why would you come with me? Do you suppose I still have sons in my womb who can become your future husbands? Go back, dear daughters—on your way, please! I’m too old to get a husband. Why, even if I said, ‘There’s still hope!’ and this very night got a man and had sons, can you imagine being satisfied to wait until they were grown? Would you wait that long to get married again? No, dear daughters; this is a bitter pill for me to swallow—more bitter for me than for you. God has dealt me a hard blow.”
