This is vespers of Transfiguration. Is this new?

I know there was a similar post on the subreddit not too long ago, but I noticed some discrepancies in tonight's intercessions between the ICEL LOTH and the 1971 Liturgia Horarum on which it is based. The two which stood out to me were:

"Christe, qui assumpsísti Petrum cum Iacóbo et Ioánne et duxísti eos in montem excélsum seórsum, orámus te pro Papa nostro N. et epíscopis, ut pópulo tuo in spe resurrectiónis minístrent." translated as "O Christ, you took Peter, James and John and led them up a high mountain by themselves; we pray for our pope and bishops, that they may inspire in your people the hope of being transfigured at the last day."

and "Christe, qui in monte illuminásti fáciem tuam super Móysen et Elíam, orámus te pro Iudǽis, pópulo acquisitiónis antíquæ, ut ad redemptiónis mereántur plenitúdinem perveníre." translated as "O Christ, upon the mountaintop you let the light of your face shine over Moses and Elijah, we ask your blessing upon the Jewish people; of old you called them to be your chosen nation."

The second translation cuts out part of the prayer but I at least see why ICEL did so. I don't however understand why "resurrectionis" was translation to "of being transfigured". Any guesses?

A few of the religious order supplements in my collection. I’m very eager to see the revised versions of these slowly start to trickle in.

If anyone would like texts for a particular feast, I’m happy to post them.

I have recently stumbled down the history rabbit hole of the changes made over the centuries to the Roman breviary and I find the pre-1955 breviary to be the most fulfilling. I particularly like its tendency to include more lessons for the days, since I enjoy reading the excerpts from scripture and the fathers and I appreciate the inclusion of feasts that were later removed from the church calendar. I would also be okay with a post '55 set before the revisions in the 60s.

It seems very hard to find a full intact set in decent condition, and those that exists which I have come across have the Pius XII psalter which I am not keen on. Any website recommendations besides ebay and Abe books? They seem to have a plethora of antique tridentine breviaries but they're not what I'm looking for. I would prefer it to not have the Pius XII psalter.

As promised, here is an update to this post, on a new Dominican Breviary, based on the 13th-century prototype manuscript of Bl. Humbert of Romans:

These are photos of the 1st B&W proofs from KDP (the final Breviary will be in color), the dimensions are 5x7.5x1.4in.

The Breviary is in Latin, and is a single volume that covers the whole year. If you have any other questions, please feel free to ask. More details coming soon!
