The Long Āgama Sūtra 5.6

5.6

爾時，有二婆羅門以堅固信往詣佛所，出家為道，一名婆悉吒，二名婆羅墮。爾時，世尊於靜室出，在講堂上彷徉經行。時，婆悉吒見佛經行，即尋速疾詣婆羅墮，而語之言：「汝知不耶？如來今者出於靜室，堂上經行，我等可共詣世尊所，儻聞如來有所言說。」時，婆羅墮聞其語已，即共詣世尊所，頭面禮足，隨佛經行。

It was then that there was a pair of priests who had gone to visit the Buddha with firm faith and left home for the path. One was named Vāsiṣṭha, and the other was named Bhāradvāja.

The Buddha had emerged from his quiet abode and was walking back and forth up in the meeting hall, and Vāsiṣṭha saw him while out walking. He quickly went to Bhāradvāja and said to him, “Did you know? The Tathāgata has emerged from his quiet abode, and he’s walking about up in the meeting hall! We could go together and pay the Bhagavān a visit. Perhaps we could hear a teaching from the Tathāgata!” When he heard this, Bhāradvāja went with Vāsiṣṭha to visit the Buddha. They bowed their heads at his feet and then walked alongside the Buddha.
