Śrīmad-Bhāgavatam
[Canto 10, Ch. 11]
PURPORT
It appears that Nanda Mahārāja regularly took his food with his two sons, Kṛṣṇa and Balarāma. Yaśodā told the other boys, “Now you should go to your homes.” Father and son generally sit together, so mother Yaśodā requested Kṛṣṇa and Balarāma to return, and she advised the other boys to go home so that their parents would not have to wait for them.
TEXT 18
धृतिधूसरिताङ्गस्त्वं पुत्र मज्जनमावह । जन्मक्षं तेऽद्य भवति विप्रेभ्यो देहि गाः शुचिः ॥१८॥

dhūli-dhūsarita-aṅgaḥ tvam —You have become covered with dust and sand all over Your body;  putra —my dear son;  majjanam āvaha —now come here, take Your bath and cleanse Yourself;  janma-ṛkṣam —the auspicious star of Your birth;  te —of You;  adya —today;  bhavati —it is;  viprebhyaḥ —unto the pure  brāhmaṇas ;  dehi —give in charity;  gāḥ —cows;  śuciḥ —being purified.
TRANSLATION
Mother Yaśodā further told Kṛṣṇa: My dear son, because of playing all day, Your body has become covered with dust and sand. Therefore, come back, take Your bath and cleanse Yourself. Today the moon is conjoined with the auspicious star of Your birth. Therefore, be pure and give cows in charity to the brāhmaṇas.
PURPORT
It is a custom of Vedic culture that whenever there is any auspicious ceremony, one should give valuable cows in charity to the  brāhmaṇas . Therefore mother Yaśodā requested Kṛṣṇa, “Instead of being enthusiastic in playing, now please come and be enthusiastic in charity.”
