CC Antya 18.38

cāhiye beḍāite aiche rātri-śeṣa haila
‘antardhāna ha-ilā prabhu’, — niścaya karila
Word for word: 
cāhiye — looking; beḍāite — wandering; aiche — in this way; rātri-śeṣa haila — the night ended; antardhāna ha-ilā — has disappeared; prabhu — the Lord; niścaya karila — they decided.
Translation: 
While they were searching for the Lord, the night ended, and thus they all decided, “Lord Śrī Caitanya Mahāprabhu has now disappeared.”
