A class of Devas, among whom virtuous men, such as those that maintain their parents and engage in harmless trades, are born (SN.vs.404).
From the Commentary (SNA. p. 379) it would appear that Sayampabhá is probably a generic name for all Devas (ye te attano ábháya andhakáram vidhamitvá álokakaranena Sayampabháti laddhanámá cha kámávacaradevá).
