After Jesus had spoken these words, He went out with His disciples across the Kidron Valley, where they entered a garden. … Jesus, knowing all that was coming upon Him, stepped forward and asked them, ”Whom are you seeking?” “Jesus of Nazareth,” they answered. Jesus said, ”I am He.” And Judas His betrayer was standing there with them. When Jesus said, ”I am He,” they drew back and fell to the ground. … “Put your sword back in its sheath!” Jesus said to Peter. “Shall I not drink the cup the Father has given Me?”
John 18:1, 4-6, 11 (BSB)
Τίνα ζητεῖτε; ... Ἐγώ εἰμι.
