The disciples were afraid (Mk 6:49-6:50)

“But when the disciples

Saw him

Walking on the sea,

They thought

It was a ghost.

They cried out.

They all saw him.

They were terrified.

But immediately,

He spoke

To them.

He said.

‘Take heart!

It is I!

Have no fear!’”

 

οἱ δὲ ἰδόντες αὐτὸν ἐπὶ τῆς θαλάσσης περιπατοῦντα ἔδοξαν ὅτι φάντασμά ἐστιν, καὶ ἀνέκραξαν

πάντες γὰρ αὐτὸν εἶδαν καὶ ἐταράχθησαν. ὁ δὲ εὐθὺς ἐλάλησεν μετ’ αὐτῶν, καὶ λέγει αὐτοῖς Θαρσεῖτε, ἐγώ εἰμι, μὴ φοβεῖσθε.

 

This incident about Jesus walking on water can be found in Matthew, chapter 14:26-27, and John, chapter 6:19-20.  In all three stories, the disciples were afraid and the response of Jesus was the same, reassuring.  Mark said that when the disciples saw him walking on the sea (οἱ δὲ ἰδόντες αὐτὸν ἐπὶ τῆς θαλάσσης περιπατοῦντα), they thought Jesus was a ghost or an apparition (ἔδοξαν ὅτι φάντασμά ἐστιν).  They cried or shouted out (καὶ ἀνέκραξαν).  They all saw him (πάντες γὰρ αὐτὸν εἶδαν) and were terrified (καὶ ἐταράχθησαν).  But immediately, Jesus spoke to them to reassure them (ὁ δὲ εὐθὺς ἐλάλησεν μετ’ αὐτῶν).  He told them to have courage and take heart (καὶ λέγει αὐτοῖς Θαρσεῖτε).  He said that he was not a ghost, but Jesus himself (ἐγώ εἰμι), so that they did not have to be afraid.  They had nothing to fear (μὴ φοβεῖσθε).  Jesus reassured his disciples, while he walked on the waters of the sea.  Once again, the disciples seemed weak or not understanding what was going on.
