It is for this reason that the Pope decided to commission the production of a new translation of the Psalms, taking into account the tradition of the Vulgate, and using the new techniques and insights of textual criticism. The work to produce the new translation was given by the Pope to the Pontifical Biblical Institute. In this "motu proprio", the pope decides that this new translation must henceforth be used in the Hours:
