to let out a loud, piercing cry: a horse's neigh, or a human shout of joy or alarm
Underneath this word is the sound a horse makes. Jeremiah uses it plainly of well fed stallions, and then of men who chase after their neighbors' wives with the same abandon. It names a high, carrying sound that is forced out of a body too full of feeling to stay quiet.
The prophets hand that same sound to people, and there it usually becomes joy. It rarely stands alone: it is paired with the ringing cry of celebration (רָנַן) in Isaiah and Jeremiah, and with plain gladness (שָׂמַח) when the city of Susa erupts at Mordecai's honoring. The partner word supplies the emotion; this word supplies the volume. Unlike the massed shout of an army or a crowd (רוּעַ), it is a single voice pitched high enough to carry.
So the feeling behind the cry comes from the setting rather than from the word itself:
- joy loud enough for a whole city to hear
- the raw cry of animals, and of people behaving like them
- a shriek of alarm as an invading army comes down the road
That is why English Bibles need so many different verbs for it. A translator has to decide what the crier is feeling before choosing a word, because the Hebrew leaves that to the context.
