הזהירנו מגלות ערות אחות האם. והוא אמרו ערות אחות אמך לא תגלה. והעובר על לאו זה במזיד חייב כרת, ובשוגג יקריב חטאת קבועה:
Sefaria Edition 2021, Translated by Rabbi Francis Nataf
He prohibited us from sexual intercourse with a sister of the mother. And that is His saying, "The nakedness of your mother's sister you shall not uncover" (Leviticus 18:13). And one who transgresses this negative commandment volitionally is [punished] by excision. But [if] inadvertent, he must sacrifice a fixed sin-offering.
