Lev 18 - Is it "uncovering nakedness" or is it "having sexual relations with"?

Question

In Leviticus 18, from verse 6 then on, there is a big chunk of passages about not "uncovering the nakedness" of relatives...or is it about not "having sexual relations with" them?

Answer 1

The Hebrew formulation is:

עֶרְוַ֥ת אֲחֽוֹת־אִמְּךָ֖ לֹ֣א תְגַלֵּ֑ה כִּֽי־שְׁאֵ֥ר אִמְּךָ֖ הִֽוא׃ (Lev 18:13, Westminster Leningrad Codex)

Literally, the term גילוי עריות means "uncovering nakedness". However, this is just a euphemism for sexual relations.

This can be seen from the following verses (Lev 18:20-23) and the parallel chapter (Lev 20:11-21) which speak more explicitly of sexual relations.

Note, however, that since Hebrew does not have explicit terms for sexual relations, all mentions of such actions use euphemisms of various sorts.
