uW Translation Notes:

Note 1 topic: figures-of-speech / infostructure

ὁ δὲ Θεὸς ἃ προκατήγγειλεν διὰ στόματος πάντων τῶν προφητῶν, παθεῖν τὸν Χριστὸν αὐτοῦ, ἐπλήρωσεν οὕτως

¬the (Some words not found in SR-GNT: ὁ Δέ Θεός ἅ προκατήγγειλεν διά στόματος πάντων τῶν προφητῶν παθεῖν τόν Χριστόν αὐτοῦ ἐπλήρωσεν οὕτως)

Your language might naturally put first in this sentence the information that God fulfilled prophecies when Christ suffered. Alternate translation: [But in this way God has fulfilled what he foretold through the mouth of all the prophets, that his Christ would suffer]

Note 2 topic: grammar-collectivenouns

διὰ στόματος πάντων τῶν προφητῶν

(Some words not found in SR-GNT: ὁ Δέ Θεός ἅ προκατήγγειλεν διά στόματος πάντων τῶν προφητῶν παθεῖν τόν Χριστόν αὐτοῦ ἐπλήρωσεν οὕτως)

Since Peter is speaking of a group of people, the prophets, it might be more natural in your language to use the plural form of mouth. Alternate translation: [through the mouths of all the prophets]

Note 3 topic: figures-of-speech / metonymy

διὰ στόματος πάντων τῶν προφητῶν

(Some words not found in SR-GNT: ὁ Δέ Θεός ἅ προκατήγγειλεν διά στόματος πάντων τῶν προφητῶν παθεῖν τόν Χριστόν αὐτοῦ ἐπλήρωσεν οὕτως)

Peter is using the mouth of the prophets to represent what they said by using their mouths. Alternate translation: [through what all the prophets said]

Note 4 topic: figures-of-speech / hyperbole

πάντων τῶν προφητῶν

˱of˲_all the prophets

Peter is using the word all as a generalization. It is true that the overall witness of Old Testament prophecy is that the Messiah would come first in humility and suffering, but not every prophet spoke specifically of the sufferings of Christ. Alternate translation: [of many prophets]
