Note 2 topic: figures-of-speech / activepassive

ἐξ οὐρανοῦ, ἐνεχθεῖσαν

If your language does not use this passive form, you can express this with an active form. Alternate translation: “having come from heaven” or “that came from heaven”

σὺν αὐτῷ, ὄντες

with him being

This is a temporal phrase that can begin with “when.” Alternate translation: “when we were with him”

Note 3 topic: writing-pronouns

σὺν αὐτῷ

with him

Here, him refers to Jesus, not God the Father. If it would be helpful in your language, you could state this reference explicitly. Alternate translation: “being with Jesus”

Note 4 topic: figures-of-speech / explicit

τῷ ἁγίῳ ὄρει

the holy mountain

The mountain Peter refers to is the mountain on which Jesus was powerfully transformed in the event known as the “transfiguration.” If it would be helpful to your readers, you could express this information explicitly. Alternate translation: “on the holy mountain on which Jesus was powerfully transformed”
