Third person: the form speaks about someone or something rather than directly as I/we or you.

Not applicable: this verb form does not use grammatical gender to make its point.

ἃ δεῖ γενέσθαι

The verb is governed by the impersonal necessity expression and takes the following infinitive γενέσθαι as its complement.

It expresses that the things already mentioned are required to come about, so the sentence presents necessity rather than mere possibility.

It does not name the subject, and it does not by itself identify the source, timing, or manner of the events beyond necessity.

High: The impersonal necessity verb directly shapes the certainty of what must take place.

Present active indicative necessity expression. marks the events as necessary rather than merely possible. Attached to the infinitive phrase about things coming to pass. Governed by the impersonal expression of necessity. The force comes from the lexical construction with the infinitive, not from present aspect alone.

How does the verse describe the coming events? It presents them as things that must take place.

Direct: The form directly supports English wording such as 'must' or 'it is necessary.'

The present form of this necessity verb should not be pressed as continuous action; the construction supplies the modal force.

Present tense always means continuous action: The present form here works in an impersonal necessity expression, so continuity is not the main interpretive point.

The witness reads δεῖ in Revelation 22:6 within the clause ἃ δεῖ γενέσθαι ἐν τάχει.

The lemma δεῖ regularly means 'it is necessary' or 'one must,' so the form carries the sense of necessity rather than simple description.

Here the impersonal singular verb points to necessity for the things spoken of to happen, and the nearby infinitive γενέσθαι supplies what is necessary.

The angelic message presents the coming events as required within God's announced purpose, not as uncertain possibilities.

This fits the wider biblical pattern in which divine announcement and fulfillment are linked to necessity within God's plan.

For readers, the form communicates urgency and certainty: what has been shown is not casual information, but required future reality.

Do not infer from the verb form alone a full timeline, a hidden subject, or more detail than the context actually gives.
