SB 5.3.19
sri-suka uvaca
iti nisamayantya merudevyah patim abhidhayantardadhe bhagavan.
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sukadeva Gosvami continued: After saying this, the Lord disappeared. The wife of King Nabhi, Queen Merudevi, was sitting by the side of her husband, and consequently she could hear everything the Supreme Lord had spoken.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
According to the Vedic injunctions, one should perform sacrifices in the company of one’s own wife. Sapatniko dharmam acaret: religious rituals should be performed with one’s wife; therefore Maharaja Nabhi conducted his great sacrifice with his wife by his side.
