Reading comprehension is not achieved by counting words. Even an engineer like me knows that much. It’s about comprehending what the words say.
What you are failing to comprehend is that the Onan story involves TWO issues:
- The refusal to continue his brother’s line.
- The sin of contraception.
Judahs tells Onan to obey the concept of the Levirate marriage outlined in Dueteronomy: "
But if a man does not want to marry his brother’s wife, she shall go up to the elders at the gate and say, “My brother-in-law refuses to perpetuate his brother’s name in Israel and does not intend to perform his duty toward me.”
Thereupon the elders of his city shall summon him and speak to him. If he persists in saying, “I do not want to marry her,”
his sister-in-law, in the presence of the elders, shall go up to him and strip his sandal from his foot and spit in his face, declaring, “This is how one should be treated who will not build up his brother’s family!”
And his name shall be called in Israel, “the house of the man stripped of his sandal.”
See what the punishment for that was under the Law of the day? Public humiliation. Not death. Onan got the death penalty. Why? Because the crime he committed was worse than refusal of Levirate marriage. He ALSO committed contraception. That’s what got him killed. (Keeping in mind that LOTS of things received the death penalty in the OT which warrant nothing of the kind under the mercy offered since then in the new covenant of Christ.)
Had he merely refused to give her children, he’d have merely been shamed. But he didn’t. He slept with her, but sterilized the encounter. Contraception. It’s plain as day.
