Study Bible

You must not have sexual relations with both a woman and her daughter.
This command is part of the Holiness Code, which outlines moral and ceremonial laws for the Israelites. The prohibition against such relationships underscores the importance of maintaining family purity and boundaries. In ancient Near Eastern cultures, family structures were central to societal stability, and violations of these boundaries were seen as threats to the social order. This command also reflects the broader biblical principle of honoring family relationships, as seen in the commandment to honor one's father and mother (Exodus 20:12).

You are not to marry her son’s daughter or her daughter’s daughter and have sexual relations with her.
This extension of the prohibition emphasizes the importance of generational boundaries within families. The inclusion of granddaughters in this command highlights the need to protect the innocence and integrity of younger family members. The Bible consistently upholds the sanctity of marriage and family, as seen in Genesis 2:24, where marriage is defined as a union between a man and a woman. This command also serves to prevent the exploitation of vulnerable family members, aligning with the biblical theme of justice and protection for the weak.

They are close relatives; it is depraved.
The term "close relatives" indicates the importance of maintaining clear distinctions within family relationships. The use of the word "depraved" suggests a moral corruption that goes against God's design for human relationships. This aligns with the broader biblical narrative that calls for holiness and separation from practices that defile (Leviticus 19:2). The New Testament echoes this call to purity, urging believers to flee from sexual immorality (1 Corinthians 6:18). The emphasis on holiness and purity in relationships points to the ultimate fulfillment in Christ, who calls His followers to live lives that reflect His righteousness.
