長阿含經 19.p33

19.p33

“Then, the nāga Nāgasā came from Vaiśāla with Takṣaka.
The Yamunā dhṛtarāṣṭras came, as did [Tiva] with their kin.
Kambalas, aśvataras, and nāgas of great miraculous ability have come.
The great nāga Airāvaṇa and the nāga [Vima] have come.
“Of the clear-eyed heavenly birds that hunt the nāga kings,
The colorful Suparṇa came to the grove from the sky.
The nāga kings are unafraid, for the Buddha [makes them safe from Suparṇa].
Greeting them with gentle words, Suparṇa took refuge in the Buddha.”
