˓is˒_saying & (Some words not found in SR-GNT: λέγει αὐτοῖς Σίμων Πέτρος Ὑπάγω ἁλιεύειν Λέγουσιν αὐτῷ ἐρχόμεθα καί Ἡμεῖς σύν σοί Ἐξῆλθον καί ἐνέβησαν εἰς τό πλοῖον καί ἐν ἐκείνῃ τῇ νυκτί ἐπίασαν οὐδέν)

Here John uses the present tense in past narration in order to call attention to a development in the story.

Note 2 topic: figures-of-speech / exclusive

ἡμεῖς

(Some words not found in SR-GNT: λέγει αὐτοῖς Σίμων Πέτρος Ὑπάγω ἁλιεύειν Λέγουσιν αὐτῷ ἐρχόμεθα καί Ἡμεῖς σύν σοί Ἐξῆλθον καί ἐνέβησαν εἰς τό πλοῖον καί ἐν ἐκείνῃ τῇ νυκτί ἐπίασαν οὐδέν)

When the disciples say We, they are speaking of themselves without Peter, so We would be exclusive. Your language may require you to mark this form.

Note 3 topic: figures-of-speech / go

ἐρχόμεθα

˓are˒_coming

Your language may state “going” rather than coming in contexts such as this. Use whichever is more natural in your language. Alternate translation: [are going]

ἐνέβησαν εἰς τὸ πλοῖον

˱they˲_boarded into (Some words not found in SR-GNT: λέγει αὐτοῖς Σίμων Πέτρος Ὑπάγω ἁλιεύειν Λέγουσιν αὐτῷ ἐρχόμεθα καί Ἡμεῖς σύν σοί Ἐξῆλθον καί ἐνέβησαν εἰς τό πλοῖον καί ἐν ἐκείνῃ τῇ νυκτί ἐπίασαν οὐδέν)

Here, got in a boat implies that they also took the boat out on the Sea of Tiberias in order to fish. You could include this information if that would be helpful to your readers. Alternate translation: [got into a boat and went fishing]
