Revelations 14:3

And they sung as it were a new song before the throne, and before the four beasts, and the elders: and no man could learn that song but the hundred and forty and four thousand, which were redeemed from the earth.

Notes:

I’m aware of this being a song we don’t currently know, but I’m comparing it to Revelations 15:3 which is “The Song of Moses”. That one is definitely a change. which is in bold because that is a thing where the verse should be using who. The wording is different than before but similar, but this stands out the most.
