Srimad Bhagavatham : 6.2.23.
tam vivaksum abhipretya mahapurusha-kinkarah,
sahasa pasyatas tasya tatrantardadhirenagha.
tam = him (Ajamila);
vivaksum = desiring to speak;
abhipretya = understanding;
mahapurusha-kinkarah = the order carriers of Lord Vishnu;
sahasa = suddenly;
pasyatah tasya = while he looked on;
tatra = there;
antardadhire = disappeared;
anagha = O sinless Maharaja Parikshit.
O sinless Maharaja Parikshit, the order carriers of the Supreme Personality of Godhead, the Vishnudutas, saw that Ajamila was attempting to say something, and thus they suddenly disappeared from his presence.
