Srimad Bhagavatam Canto 10, Chapter 44, Text 16

SB 10.44.16

pratar vrajad vrajata avisatas ca sayam
 gobhih samam kvanayato ’sya nisamya venum
nirgamya turnam abalah pathi bhuri-punyah
 pasyanti sa-smita-mukham sa-dayavalokam
 
Translation: 
 
When the gopis hear Krsna playing His flute as He leaves Vraja in the morning with His cows or returns with them at sunset, the young girls quickly come out of their houses to see Him. They must have performed many pious activities to be able to see Him as He walks on the road, His smiling face mercifully glancing upon them.
