In the English Bible, the word "unicorn" is used 9 times. What can we find out by looking at the Latin and Hebrew texts that it was translated from? To compare English with Greek, Latin, and Hebrew texts of the Bible, we will use the Tetrapla. The Tetrapla uses Neo-Paleo encoding to transliterate all Bible texts into English letters, no matter what the source language.

rinocerotis, rinoceros, rinocerota, unicornium, monocerotis, unicornes.
Rinocerotis is used four times, the other words are used once each. From this, it does seem that the Romans understood the text to refer to a rhinocerous.
RAM, RIM, RMIM, RAMIM, RAIM.
RAM is used thrice, RIM twice, RMIM once, RAMIM twice, and RAIM once. The Hebrew word CRAIM becomes RAIM. The letter kaph (C) in front is a suffix, that means "like". "Like a RAIM". Another interesting detail is how the spelling of RAM changes over time. In the book of Job it is RIM. Job is the oldest book in the Bible, written in the Edomite dialect of Hebrew.
It is interesting to see so many different spellings of RAM in the Psalms. This isn't unusual in the Psalms, noted for its mispellings and archaic forms of Hebrew.
RAMIM is the plural form of RAM, so we can count RAMIM the same as RAM. RMIM is the plural form of RM. It looks like the poet forgot to put the A in RM in Psalm 22:21. I note that the English doesn't agree with the Hebrew when it comes to the plural forms. So the Hebrew QRN for Horn and RAM for Unicorn need to be checked in all 9 instances to see what is the correct reading.
This is just a preliminary gathering of data, more study has to be done to draw any conclusions about the Biblical unicorn.
