עֶרְוַ֥ת אֲחֽוֹת־אִמְּךָ֖ לֹ֣א תְגַלֵּ֑ה כִּֽי־שְׁאֵ֥ר אִמְּךָ֖ הִֽוא׃ (ס)
Thou shalt not uncover the nakedness of thy mother’s sister; for she is thy mother’s near kinswoman.
Targum Jonathan on Leviticus
The nakedness of thy mother's sister thou shall not dishonour; for she is of kin to thy mother's flesh.
