Genesis 19:34

19:34 So in the morning the older daughter ¹  said to the younger, “Since I had sexual relations with my father last night, let’s make him drunk again tonight. ²  Then you go and have sexual relations with him so we can preserve our family line through our father.” ³ 

Genesis 30:15

30:15 But Leah replied, ⁴  “Wasn’t it enough that you’ve taken away my husband? Would you take away my son’s mandrakes too?” “All right,” ⁵  Rachel said, “he may sleep ⁶  with you tonight in exchange for your son’s mandrakes.”

[19:34]  ¹ tn Heb “the firstborn.”

[19:34]  ² tn Heb “Look, I lied down with my father. Let’s make him drink wine again tonight.”

[19:34]  ³ tn Heb “And go, lie down with him and we will keep alive from our father descendants.”

[30:15]  ⁴ tn Heb “and she said to her”; the referent of the pronoun “she” (Leah) has been specified in the translation for clarity.

[30:15]  ⁵ tn Heb “therefore.”

[30:15]  ⁶ tn Heb “lie down.” The expression “lie down with” in this context (here and in the following verse) refers to sexual intercourse. The imperfect verbal form has a permissive nuance here.
