I can't help but wonder if this was the jews explaining the divergence of the semitic languages to the point where they wouldn't be able to understand Babylonian and Akkadian despite them being related to Hebrew and having ended up on the same side of older splits like those from other afro-asiatic languages like the egyptian, kushitic, and amazigh branches.
Genesis 11:6 NIV - The Lord said, “If as one people speaking the same language they have begun to do this, then nothing they plan to do will be impossible for them.
Recently played Chants of Sennaar. It's a chill and puzzl-y game while specifically covering the languages aspect of the Tower of Babel story. Can recommend.
