But you shall receive the power of the Holy Spirit, passing over you, and you shall be witnesses for me in Jerusalem, and in all Judea and Samaria, and even to the ends of the earth. (Acts 1:8)
ἀλλὰ λήμψεσθε δύναμιν ἐπελθόντος τοῦ ἁγίου πνεύματος ἐφ᾽ ὑμᾶς καὶ ἔσεσθέ μου μάρτυρες ἔν τε Ἰερουσαλὴμ καὶ [ἐν] πάσῃ τῇ Ἰουδαίᾳ καὶ Σαμαρείᾳ καὶ ἕως ἐσχάτου τῆς γῆς.
sed accipietis virtutem, superveniente Sancto Spiritu in vos, et eritis mihi testes et in Ierusalem et in omni Iudaea et Samaria et usque ad ultimum terrae.
The Greek noun μάρτυς is taken from judicial vocabulary, where it means a person who testifies about events in which he took part or about people and situations he knows directly. The basis for testifying about Jesus, for witnessing about Him to others, is my intimacy with Him, being close to Him, listening to Him, eating His Body and Blood… Fortunately, I am not alone in this because the Lord sends me the Spirit who gives me strength and enables me for this mission.
