Śrīmad-Bhāgavatam
[Canto 10, Ch. 5]
PURPORT
Vasudeva and Nanda Mahārāja were so intimately connected that they lived like brothers. Furthermore, it is learned from the notes of Śrīpāda Madhvācārya that Vasudeva and Nanda Mahārāja were stepbrothers. Vasudeva's father, Śūrasena, married a  vaiśya  girl, and from her Nanda Mahārāja was born. Later, Nanda Mahārāja himself married a  vaiśya  girl, Yaśodā. Therefore his family is celebrated as a  vaiśya  family, and Kṛṣṇa, identifying Himself as their son, took charge of  vaiśya  activities ( kṛṣi-go-rakṣya-vāṇiyyam ). Balarāma represents plowing the land for agriculture and therefore always carries in His hand a plow, whereas Kṛṣṇa tends cows and therefore carries a flute in His hand. Thus the two brothers represent  kṛṣi-rakṣya  and  go-rakṣya .

TRANSLATION
When Nanda Mahārāja heard that Vasudeva had come, he was overwhelmed with love and affection, being as pleased as if his body had regained its life. Seeing Vasudeva suddenly present, he got up and embraced him with both arms.
PURPORT
Nanda Mahārāja was older than Vasudeva. Therefore Nanda Mahārāja embraced him, and Vasudeva offered him  namaskāra .
