> (Formerly in Israel, when a man went to inquire of God, he said, “Come, let us go to the seer”; for he who is now called a prophet was formerly called a seer.)

I love that one because it translates so well into English because we also have an older and a newer word for close enough to the same thing. Though when saying older and newer I should note that the words “prophet” and “seer” have been used consistently since the very first English translation, Wycliffe’s in ~1382. Maybe it’s more the feel of the words. (In Bible Gateway’s catalogue of English translations, only the CEV doesn’t use both of those words: <https://www.biblegateway.com/verse/en/1sam9.9>; I disqualify OJB as not English.)

That’s the only one I can think of off the top of my head that’s specifically about language, but there are plenty of others about changed customs over time, in Old and New Testaments.
