Genesis 30:3-5

Wycliffe Bible

³ And she said, I have an handmaid Bilhah; enter thou [in] to her that she child on my knees, and that I have sons of her. (And she said, I have a slave-girl Bilhah; sleep thou with her, so that she can bear some children, and lay them on my knees, and so I shall have sons by her.)

⁴ And she gave to him Bilhah into matrimony; and when her husband had entered [in] to her,

⁵ she conceived, and childed a son.
