SB 10.31.4

na khalu gopīkā-nandano bhavān
 akhila-dehinām antarātma-dṛk
vikhanasārthito viśva-guptaye
 sakha udeyivān sātvatāṁ kule
Word for word: 
na — not; khalu — indeed; gopikā — of the gopī, Yaśodā; nandanaḥ — the son; bhavān — Your good self; akhila — of all; dehinām — embodied living entities; antaḥ-ātma — of the inner consciousness; dṛk — the seer; vikhanasā — by Lord Brahmā; arthitaḥ — prayed for; viśva — of the universe; guptaye — for the protection; sakhe — O friend; udeyivān — You arose; sātvatām — of the Sātvatas; kule — in the dynasty.
Translation: 
You are not actually the son of the gopī Yaśodā, O friend, but rather the indwelling witness in the hearts of all embodied souls. Because Lord Brahmā prayed for You to come and protect the universe, You have now appeared in the Sātvata dynasty.
Purport: 

The gopīs here imply, “Since You have descended to protect the entire universe, how can You neglect Your own devotees?”
