They all said that they would not deny Jesus (Mk 14:31-14:31)

“But Peter

Said vehemently.

‘Even though

I must die

With you,

I will not deny you.’

All of them

Said the same.”

 

ὁ δὲ ἐκπερισσῶς ἐλάλει Ἐὰν δέῃ με συναποθανεῖν σοι, οὐ μή σε ἀπαρνήσομαι. ὡσαύτως δὲ καὶ πάντες ἔλεγον

 

This is almost word for word in Matthew, chapter 26:35.  Mark indicated that Peter kept emphatically saying to Jesus (δὲ ἐκπερισσῶς ἐλάλει) that even if it was necessary that he had to die with Jesus (Ἐὰν δέῃ με συναποθανεῖν σοι), he would never deny or repudiate him (οὐ μή σε ἀπαρνήσομαι).  Then all the other disciples said the same thing (ὡσαύτως δὲ καὶ πάντες ἔλεγον).  Thus, all the 12 apostolic leaders exaggerated their own loyalty to Jesus.

Jesus prayed alone in the early morning (Mk 1:35-1:35)

“In the morning,

While it was still

Very dark,

Jesus got up.

He went out

To a deserted place.

There he prayed.”

 

Καὶ πρωῒ ἔννυχα λίαν ἀναστὰς ἐξῆλθεν καὶ ἀπῆλθεν εἰς ἔρημον τόπον, κἀκεῖ προσηύχετο.

 

There is something similar in Luke, chapter 4:42, but there is nothing about Jesus praying there.  He simply went out to a deserted place at daybreak, following the healings of the evening before as here.  Mark said that in the morning (Καὶ πρωῒ), while it was still very dark or still nighttime (ἔννυχα λίαν), Jesus rose up or got up (ἀναστὰς).  He went out and left for a deserted, desolate, or solitary place (ἐξῆλθεν καὶ ἀπῆλθεν εἰς ἔρημον τόπον), where he prayed (κἀκεῖ προσηύχετο).  Jesus left the other disciples behind early in the morning before daybreak.  This would be an important habit of Jesus, praying alone.
