to prophesy: to act as a prophet, speaking out a message presented as God's word (whether the speaker truly received it or not)
To prophesy is to act as God's spokesman: to say out loud a message put forward as coming from him. It is not, at its core, predicting the future on one's own initiative. The stress falls on delivering the message to the people it is meant for. That is why God can simply command the act: "Prophesy against the mountains of Israel," he tells Ezekiel again and again, who then says exactly what God gives him.
The word itself is neutral about whether the message is real. The same verb covers both true and false prophecy, because the outward act looks identical: someone stands up and announces, "This is what the LORD says." What divides them is the source. The true prophet carries a word God actually gave; the fraud speaks the invention of his own heart while claiming the same authority. Jeremiah and Ezekiel use the word relentlessly for both, often in the same breath, precisely to expose impostors who sound just like the real thing.
A cluster of texts uses the word for prophesying as visible, sometimes frenzied behavior:
- Saul falls in among a band of prophets and does as they do
- the elders around Moses briefly break out in it
- the prophets of Baal work themselves into a frenzy
Here the word leans on the person's seized, altered conduct rather than on a quotable message. A different corner of the Bible even applies it to the temple singers of Chronicles, who "prophesy" with harps and lyres as inspired worship.
Older scholars tried to pin the frenzied sense to one grammatical form of the verb and the sober, authoritative sense to another. That neat split cannot be sustained: the same forms cross freely between the two, so any ecstatic coloring comes from the setting of a passage, not from the word itself. The senses below sort the true spokesman, the pretender, the spirit-seized behavior, and the inspired singer, but the verb underneath them all simply names the act of functioning as a prophet.
Nuances
Disputed
Whether the reflexive stem (Hitpael) marks a genuinely distinct kind of prophesying, especially ecstatic or behavioral activity, or is essentially interchangeable with the ordinary passive stem (Niphal) so that any ecstatic coloring is contextual rather than built into the word.
- majorityThe two stems are largely synonymous in the received text; ecstasy is not built into the root, and any behavioral coloring comes from the narrative setting.; Robert R.

- minorityIn narrative and polemical texts the reflexive stem was used as a depreciative register, coloring the activity as the disreputable behavior of the old prophetic bands.; Klaus-Peter Adam, "'And He Behaved Like a Prophet Among Them' (1 Sam 10:11b): The Depreciative Use of נבא Hitpael," Die Welt des Orients 39 (2009): 3-57
