Hupozugion denotes the animal described as mounted by a king and as speaking with a human voice.

The two verses use the term for an animal: in Matthew 21:5 it is the animal on which the king is mounted, while in 2 Peter 2:16 it is mute yet speaks with a human voice.

1. Animal in a mounted royal scene · dominant

   In Matthew 21:5, the genitive singular neuter form occurs in the clause about the king coming gentle and mounted; the APB renders the scene as mounted “upon a donkey” and then mentions a colt as the son of a donkey.

   Matthew 21:5
2. Animal that speaks in rebuke · occasional

   In 2 Peter 2:16, the nominative singular neuter form is the subject described as mute but speaking with a human voice; the APB renders it as a donkey whose speech restrained the prophet's insanity.

   2 Peter 2:16

In the Anselm Project Bible: The APB presents the animal as “a donkey” in both verses: one is mounted by a king in Matthew 21:5, and one speaks in 2 Peter 2:16. These renderings confirm the scenes rather than independently define the term.
