This verse underscores the custom of preserving a family line through levirate marriage, revealing the cultural practice tying heritage, property, and God’s covenant promises into one.
Then Judah said to Onan, “Go in to your brother’s wife, and perform your duty as a brother-in-law to her, and raise up offspring for your brother.” (v.8) In this passage, Judah—who lived around the early 19th century BC as the fourth son of Jacob—proclaims a responsibility known in ancient Israelite custom as levirate marriage. According to this practice, if a man died without children, his brother was to marry the widow so that the deceased brother’s family line would continue (as also seen in Deuteronomy 25:5 and Ruth 3:1). Judah’s instruction to Onan is to fulfill that obligation on behalf of his late brother, Er, and provide offspring for the deceased brother’s lineage. Levirate marriage held significant importance for Israelite inheritance and property rights because it secured land within the family line and protected widows from destitution.Then Judah said to Onan… (v.8) also reveals Judah’s role as the family patriarch at this time, emphasizing his authority to command Onan to take Tamar, Er’s widow, as wife. Historically, Judah fits into the patriarchal era, a few generations removed from Abraham, thus placing him and his sons within God’s unfolding covenant promises. Onan’s refusal to produce an heir for his brother (detailed in the following verses) exemplifies the tension between God’s designs for preserving a family inheritance and human reluctance when personal economic interests are threatened.By instructing Onan, Judah sought to ensure that Tamar, his daughter-in-law, would still be part of the larger covenant community through the continuation of Er’s lineage. From God’s perspective, this command had spiritual and communal dimensions: it upheld justice for the widow, preserved the broader family line, and pointed forward to the legacy that would extend all the way to King David and ultimately to Jesus, who also descended from Judah.
