This verse in the King James

King James wording
Thou shalt not uncover the nakedness of thy daughter in law: she is thy son’s wife; thou shalt not uncover her nakedness.

The repeated “uncover” brackets the declaration that she is the son’s wife, making the relationship itself the boundary.

This verse names a present relational boundary: the daughter-in-law is her husband’s wife, and her nakedness is forbidden to her father-in-law. The repeated prohibition leaves no opening for household closeness to become sexual access.

WHAT THIS UNDOES

It undoes the lie that a father’s place in the household gives him sexual access to his son’s wife; the verse names her relationship and repeats the prohibition.

תְגַלֶּה

tegalleh

GROWS FROM

גלה

To uncover, expose, or reveal; in another usage, this root also appears in words for going into exile.

The verb translated “uncover” belongs to a root that also means “reveal” and appears in the language of exile. Here, “nakedness” and the kinship clause anchor it in sexual exposure, while its wider range lets the word carry the sense of what is brought out from covering.

ALSO GROWS

galah: Uncover, reveal; also go into exile in another use of the root.

גָּלָה

This root’s range links uncovering with exposure; in this verse, the surrounding words specify the sexual sense.

niglah: Be revealed or uncovered.

נִגְלָה

This related form makes visible the root’s movement from hidden to exposed, sharpening the force of the prohibition.

Kinship creates a sexual boundary that household closeness does not erase.

Do not draw near to any flesh of your flesh, to uncover nakedness. I am the LORD.
Leviticus 18:6 · SDVThe general boundary against uncovering near kin supplies the rule that this verse applies to a daughter-in-law.
A man shall not take his father's wife, nor uncover his father's wing.
Deuteronomy 22:30 · SDVThe prohibition treats a father’s wife as a protected relation rather than as sexual access.
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 verse names a father’s wife as a sexual relation that violates the family boundary.
A man shall not take his father's wife, nor uncover his father's wing.
Deuteronomy 22:30 · SDV

Deuteronomy uses the same root, ⁨גלה⁩ (galah, uncover), for the mirrored boundary involving a father’s wife. Together, the verses show the prohibition holding across both directions of the family bond.
