Context
48 Seeing them distressed in rowing, for the wind was contrary to them, about the fourth watch of the night he came to them, walking on the sea; and he would have passed by them,

50 for they all saw him and were troubled. But he immediately spoke with them and said to them, “Cheer up! It is I! Don’t be afraid.”
