Wasn’t actually today, but it’s an interesting etymology. Old Arabian speaks “majus” because they lack a hard G sound, similar to Japanese lacking L sound

That’s beside the point here. The story exists and the etymology of Magus helps contextualize an often overlooked detail, that the three wise men were zoroastrian priests. Somewhat related XKCD - https://what-if.xkcd.com/25/
