The Long Āgama Sūtra 2.95

2.95

爾時，世尊即從座起，詣於講堂，就座而坐，告諸比丘：「此土飢饉，乞求難得，汝等宜各分部，隨所知識，詣毘舍離及越祇國，於彼安居，可以無乏。吾獨與阿難於此安居。所以然者？恐有短乏。」是時，諸比丘受教即行，佛與阿難獨留。

The Bhagavān then rose from his seat and went to the meeting hall. He prepared a seat and sat down. He then told the monks, “There’s a famine in this region that’s making it difficult to solicit alms. It would be best for all of you to split into groups and visit people you know in Vaiśālī and Vṛji where there’s no shortage of food. I will stay here in this safe abode with Ānanda. Why is that? It’s dangerous when there’s such shortages.” The monks accepted his instruction and did so. The Buddha and Ānanda stayed there by themselves.
