to cry out: to raise the voice into a loud, carrying call that is meant to be heard.
This is the plain Greek verb for lifting the voice to a shout. Its whole force is volume and reach: a voice pushed loud enough to cross a distance and land on whoever is meant to hear it. Almost every time it appears, the words of the shout follow immediately after, so the loudness is in service of something the shouter needs said.
The same shout does very different work depending on who raises it:
- the announcement of a herald, the voice in the wilderness that all four Gospels use to introduce John the Baptist
- an urgent appeal to someone who can help, a father calling about his son and a blind beggar calling for mercy as Jesus passes
- the massed shouting of a hostile crowd pressing a charge, in Thessalonica and again before a Roman governor
- a cry forced out by extremity, from Jesus at the end on the cross and from unclean spirits leaving those they had held
- a burst of gladness, the childless woman commanded to break out and shout
What holds these together is the voice rather than the feeling behind it. The Greek word for a scream (κράζω) leans toward a ragged and sometimes wordless cry, and the ordinary word for calling or summoning a person (φωνέω) need not be loud at all. This word sits between them as the clear loud call. In Galatians the two halves of one command stand side by side, bursting out (ῥήγνυμι) and then shouting.
It is also the word the Greek Old Testament reaches for when Israel cries out under oppression, standing in for the Hebrew verb for that outcry (צָעַק) and for the broad Hebrew verb for calling aloud (קָרָא). That background is audible in the parable of the persistent widow, where God's chosen ones cry to him day and night and are heard.
