“When she saw Peter
Were with Jesus,
The man from Nazareth.’”
καὶ ἰδοῦσα τὸν Πέτρον θερμαινόμενον ἐμβλέψασα αὐτῷ λέγει Καὶ σὺ μετὰ τοῦ Ναζαρηνοῦ ἦσθα τοῦ Ἰησοῦ.
This is similar to Matthew, chapter 26:69, and Luke, chapter 22:56. John, chapter 18:17, has just a woman without any further description. Mark said that Peter was warming himself in the high priest’s courtyard (καὶ ἰδοῦσα τὸν Πέτρον θερμαινόμενον). This young servant girl or maid of the high priest was looking or staring at Peter (ἐμβλέψασα αὐτῷ). She said to Peter (λέγει) that he had been with Jesus, the man from Nazareth (Καὶ σὺ μετὰ τοῦ Ναζαρηνοῦ ἦσθα τοῦ Ἰησοῦ), and not a Galilean as in Matthew. She had spotted Peter with Jesus. She knew that Jesus was from Nazareth. Now she recognized Peter. She may have seen Jesus and his followers somewhere beforehand. People judge you by your company. Would you deny your friends?
