OET interlinear LEV 20:12

uW Translation Notes:

Note 1 topic: figures-of-speech / euphemism

וְ⁠אִ֗ישׁ אֲשֶׁ֤ר יִשְׁכַּב֙ אֶת־כַּלָּת֔⁠וֹ

and,a_man (Some words not found in UHB: and,a_man which/who lies_with DOM his/its=daughter-in-law to_die they_must_die both_of=them perversion they_had_acquired blood(s)_of,their [are]_on,them )

This is a polite way of speaking of sexual relations. See how you handled the similar expression in the previous verse. Alternate translation: [And a man who sleeps with his daughter-in-law] or [And a man who has sexual relations with his daughter-in-law]

Note 2 topic: figures-of-speech / explicit

אֶת־כַּלָּת֔⁠וֹ

DOM (Some words not found in UHB: and,a_man which/who lies_with DOM his/its=daughter-in-law to_die they_must_die both_of=them perversion they_had_acquired blood(s)_of,their [are]_on,them )

A daughter-in-law is the wife of one’s son. If it would be helpful to your readers, you could include this information. Alternate translation: [with his son’s wife]

Note 3 topic: figures-of-speech / reduplication

מ֥וֹת יוּמְת֖וּ שְׁנֵי⁠הֶ֑ם

to_die they_must_die (Some words not found in UHB: and,a_man which/who lies_with DOM his/its=daughter-in-law to_die they_must_die both_of=them perversion they_had_acquired blood(s)_of,their [are]_on,them )

See how you translated this exact phrase in 20:11.

Note 4 topic: figures-of-speech / abstractnouns

תֶּ֥בֶל עָשׂ֖וּ

(Some words not found in UHB: and,a_man which/who lies_with DOM his/its=daughter-in-law to_die they_must_die both_of=them perversion they_had_acquired blood(s)_of,their [are]_on,them )

Here the abstract noun perversion refers to a behavior that is considered to be far outside the bounds of what Yahweh intends for people to do. If your language does not use an abstract noun for the idea of perversion, you could express the same idea in another way. Alternate translation: [The thing they have done is perverted and disgusting] or [Such behavior is forbidden because it is so disgusting and perverse]

Note 5 topic: figures-of-speech / idiom

דְּמֵי⁠הֶ֥ם בָּֽ⁠ם

(Some words not found in UHB: and,a_man which/who lies_with DOM his/its=daughter-in-law to_die they_must_die both_of=them perversion they_had_acquired blood(s)_of,their [are]_on,them )

See how you handled the similar expression in 20:9.
