SB 10.65.3
ciram nah pahi dasarha
sanujo jagad-isvarah
ity aropyankam alingya
netraih sisicatur jalaih
Translation:
[Nanda and Yasoda prayed,] “O descendant of Dasarha, O Lord of the universe, may You and Your younger brother Krsna ever protect us.” Saying this, they raised Sri Balarama onto their laps, embraced Him and moistened Him with tears from their eyes.
Purport:
Srila Jiva Gosvami comments on this verse as follows: “Nanda and Yasoda prayed to Sri Balarama, ‘May You, along with Your younger brother, protect us.’ Thus they expressed their respect for the fact that He is the elder brother, and they also showed how much they considered Him their own son.”
