With Ambaṭṭha 1.8.5

1.8.5

“eso, ambaṭṭha, vihāro saṃvutadvāro, tena appasaddo upasaṅkamitvā ataramāno āḷindaṃ pavisitvā ukkāsitvā aggaḷaṃ ākoṭehi, vivarissati te bhagavā dvāran”ti.

“Ambaṭṭha, that’s his dwelling, with the door closed. Approach it quietly, without hurrying; go onto the porch, clear your throat, and knock on the door-panel. The Buddha will open the door.”
