SB 9.23.37
aham bandhyasapatni ca
snusa me yujyate katham
janayisyasi yam rajñi
tasyeyam upayujyate
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Saibya said, “I am sterile and have no co-wife. How can this girl be my daughter-in-law? Please tell me.” Jyamagha replied, “My dear Queen, I shall see that you indeed have a son and that this girl will be your daughter-in-law.”
