Pour out
'Pouring out the vials upon the earth, which contained the plagues,' in Revelation 16:1, signifies influx of the reformed into the church, or into people who study and receive the doctrine of justification by faith alone.

Cry
As with most common verbs, the spiritual meaning of “crying” or “crying out” (meaning a shout or wail, not weeping) is highly dependent on context. Who is crying out? To whom? Why? In most cases, though, crying has to do with speaking falsely, and of the emotions arising from the conflict between truth and falsity. When people cry out in distress it is most often an indication that they are being overwhelmed by false ideas. In other cases – especially regarding more joyful cries – it is a celebration of the triumph of truth.
