This verse in the King James

King James wording
The nakedness of thy father’s wife’s daughter, begotten of thy father, she is thy sister, thou shalt not uncover her nakedness.

A different mother does not undo the bond of birth: the daughter begotten by your father is named your sister.

The verse names the daughter of your father’s wife, when she is begotten by your father, as your sister. It draws a clear boundary around her body, and that kinship remains real even when the household arrangement is complicated.

WHAT THIS UNDOES

The belief that having a different mother makes her not your sister is undone: the verse says your shared father makes her your sister.

מוֹלֶדֶת

moledet

GROWS FROM

ילד

To bear or beget; to bring forth by birth.

“born of” in this verse is moledet. The verse grounds the kinship in birth: ⁨מוֹלֶדֶת⁩ (moledet, begotten) comes from ⁨יָלַד⁩ (yalad, to bear or beget). The English phrasing makes the father’s role explicit, and the root ties that fact of birth to the word for a child.

ALSO GROWS

yalad: To bear, bring forth, or beget.

יָלַד

This is the verb behind ⁨מוֹלֶדֶת⁩ (moledet), linking the sister’s identity to being born of the same father.

yeled: A child.

יֶלֶד

The shared root keeps the passage’s kinship claim anchored in the child born, not merely in the household she belongs to.

תְגַלֶּה

tegalleh

GROWS FROM

גלה

To uncover, expose, or reveal.

The command uses ⁨גָּלָה⁩ (galah, to uncover or reveal), the same root family as ⁨גִּלּוּי⁩ (gilluy, revelation or uncovering). Here “uncover” names sexual exposure, so the verse’s boundary is expressed through an image of opening what is meant to remain covered.

ALSO GROWS

galah: To uncover or reveal.

גָּלָה

This is the root verb behind ⁨תְגַלֶּה⁩ (tegalleh), making the act a deliberate exposure.

gilluy: Revelation or uncovering.

גִּלּוּי

This related noun preserves the root’s sense of making something exposed or visible, which sharpens the force of the verse’s boundary.

Scripture treats kinship as a boundary around sexual exposure, even when household arrangements or maternal lines differ.

And if a man take his sister, his father's daughter or his mother's daughter, and see her nakedness, and she see his nakedness; it is a disgrace; they shall be cut off before the eyes of the children of their people. He has uncovered his sister's nakedness; he shall bear his crookedness.
Leviticus 20:17 · SDVThis verse names a sister through either parent and directly connects kinship with the boundary against uncovering.
Cursed be he who lies with his sister, the daughter of his father or the daughter of his mother. And all the people shall say, Amen.
Deuteronomy 27:22 · SDVThe shared father or shared mother is enough for the relationship to be named as sister.
It is heard commonly that there is the trade of bodies among you, and such trade as is not even named among the nations, that one should hold his father's wife.
1 Corinthians 5:1 · SDVThe father’s household relation does not erase the kinship boundary named in the passage.
And Adam knew Eve his wife, and she conceived and bore Cain, the gotten one, and she said, I have gotten a man from the LORD.
Genesis 4:1 · SDV

The word “bare” translates ⁨וַתֵּלֶד⁩ (vatteled), from the same root ⁨ילד⁩ (yalad, to bear or beget) as ⁨מוֹלֶדֶת⁩ (moledet) in Leviticus 18:11. The shared root shows birth as the concrete basis for the kinship the verse names.
