'Once' in the Bible

at once, therefore, I sent to thee; thou also didst do well, having come; now, therefore, are we all before God present to hear all things that have been commanded thee by God.'

who, at once, having taken soldiers and centurions, ran down upon them, and they having seen the chief captain and the soldiers, did leave off beating Paul.

and a plot having been intimated to me against this man -- about to be of the Jews -- at once I sent unto thee, having given command also to the accusers to say the things against him before thee; be strong.'
