John 19:35
Nestle 1904 Greek New Testament · Berean Standard Bible
καὶ ὁ ἑωρακὼς μεμαρτύρηκεν καὶ ἀληθινὴ αὐτοῦ ἐστιν ἡ μαρτυρία καὶ ἐκεῖνος οἶδεν ὅτι ἀληθῆ λέγει ἵνα καὶ ὑμεῖς πιστεύητε
The one who saw it has testified to this, and his testimony is true. He knows that he is telling the truth, so that you also may believe.
