H5039 - nevalah

Strong's: H5039 · BLB lookup Pronunciation: neh-vaw-LAH Part of speech: feminine noun OT occurrences: ~13 times Root: from H5036 nabal, "fool, senseless, godless", the nabal is not merely intellectually deficient but morally and spiritually corrupt (cf. Psalm 14:1, "the fool says in his heart, there is no God").

Semantic range

Nevalah is not ordinary foolishness. It is disgraceful, wanton, morally outrageous conduct, a crime that violates the covenant order and shames the community. BDB glosses it "senselessness, disgraceful folly; especially of sins of unchastity." It is the vocabulary of moral horror.

"An outrage in Israel"

The word repeatedly appears in the fixed formula nevalah beYisrael, "an outrage / disgraceful thing in Israel," which brands an act as intolerable within the covenant people:

Genesis 34:7, the rape of Dinah: Jacob's sons are grieved and angry "because he had done an outrage (nevalah) in Israel by lying with Jacob's daughter."
Deuteronomy 22:21, sexual sin branded nevalah.
Joshua 7:15, Achan's covenant-breaking called nevalah.
Judges 19:23-24; 20:6, 10, the Gibeah atrocity against the Levite's concubine, repeatedly named nevalah, the outrage that ignites civil war.
2 Samuel 13:12, Tamar to Amnon: "do not do this disgraceful thing (nevalah)."

In every one of these sexual-crime contexts, nevalah is the narrator's or a character's moral verdict of condemnation.

Apologetic load

Scripture condemns sexual violence in its own strongest moral vocabulary. The recurring nevalah verdict is decisive against the claim that the Old Testament is indifferent to or approving of rape. When Dinah, Tamar, and the Gibeah concubine are violated, the text calls it an outrage in Israel. See Rape Only Condemned When Unmarried Objection Defeater and Biblical Marriage Consent Objection Defeater.
Tamar's own word. That Tamar names the impending act nevalah (2 Samuel 13:12) shows a woman's refusal treated as morally right and its override as disgraceful, directly relevant to the consent question.
The moral-realism frame. Nevalah presupposes an objective covenantal-moral order in which some acts are simply outrageous. This is the furniture an atheist objection borrows to condemn the very text that supplies it.
