θεασάμενος αὐτοὺς ἀκολουθοῦντας

˓having˒_seen (Some words not found in SR-GNT: στραφείς Δέ ὁ Ἰησοῦς καί θεασάμενος αὐτούς ἀκολουθοῦντας λέγει αὐτοῖς Τί ζητεῖτε οἱ Δέ εἶπαν αὐτῷ Ῥαββί ὅ λέγεται μεθερμηνευόμενον Διδάσκαλε Ποῦ μένεις)

John is leaving out a word that a sentence would need in many languages to be complete. If it would be helpful in your language, you could supply this word from the context. Alternate translation: [having seen them following him]

Note 3 topic: figures-of-speech / pastforfuture

λέγει

˱he˲_˓is˒_saying

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

ποῦ μένεις

(Some words not found in SR-GNT: στραφείς Δέ ὁ Ἰησοῦς καί θεασάμενος αὐτούς ἀκολουθοῦντας λέγει αὐτοῖς Τί ζητεῖτε οἱ Δέ εἶπαν αὐτῷ Ῥαββί ὅ λέγεται μεθερμηνευόμενον Διδάσκαλε Ποῦ μένεις)

Alternate translation: [where are you spending the night]

Note 4 topic: figures-of-speech / explicit

ποῦ μένεις?

(Some words not found in SR-GNT: στραφείς Δέ ὁ Ἰησοῦς καί θεασάμενος αὐτούς ἀκολουθοῦντας λέγει αὐτοῖς Τί ζητεῖτε οἱ Δέ εἶπαν αὐτῷ Ῥαββί ὅ λέγεται μεθερμηνευόμενον Διδάσκαλε Ποῦ μένεις)

This question is the answer to the question Jesus just asked in the previous sentence. It is a way for the two men to imply that they would like to have a private conversation with Jesus at the place where he was staying. You could include this information if that would be helpful to your readers. Alternate translation: [where are you staying? We would like to speak with you privately.]
