Study Bible

You must not have sexual relations
This phrase is a direct command, emphasizing the prohibition of certain sexual behaviors. The Hebrew root here is "גלה ערוה" (galah ervah), which means to uncover nakedness, a euphemism for sexual relations. This command is part of a larger set of laws given to the Israelites to maintain holiness and purity, distinguishing them from the surrounding nations whose practices were often morally corrupt.

with your mother’s sister
The Hebrew term for "mother’s sister" is "דֹּדָה" (dodah), which specifically refers to an aunt on the maternal side. This relationship is highlighted to stress the closeness of family ties and the importance of maintaining respect and boundaries within the family unit. In ancient Near Eastern cultures, family structure was crucial, and maintaining its sanctity was a reflection of one's respect for God's order.

for she is your mother’s close relative
The phrase "close relative" in Hebrew is "שְׁאֵר אִמֶּךָ" (she'er immeka), which underscores the intimate familial bond. This part of the verse reiterates the reason for the prohibition: the preservation of family integrity and the prevention of confusion and disorder within the family lineage. Historically, these laws served to protect the family unit from internal strife and to uphold the community's moral standards.
