Ekottaragama (Sanskrit fragments) 24.5.126

24.5.126

是時，五百弟子白迦葉言：「我等先亦有心於沙門瞿曇，當降龍時，尋欲歸命。若師自歸瞿曇者，我等五百弟子盡自歸於瞿曇所。」

His 500 disciples then said to Kāśyapa, “We had that thought about the ascetic Gautama before when he tamed the serpent. We immediately wanted to take refuge in him. If the teacher himself takes refuge in Gautama, then we 500 disciples will all take refuge in Gautama as well.”
