“The Holy Spirit
Will teach you
At that very hour
What you ought to say.”
τὸ γὰρ Ἅγιον Πνεῦμα διδάξει ὑμᾶς ἐν αὐτῇ τῇ ὥρᾳ ἃ δεῖ εἰπεῖ
Luke had Jesus explain why they should not worry. The Holy Spirit (τὸ γὰρ Ἅγιον Πνεῦμα) would teach them (διδάξει ὑμᾶς) at that very hour (ἐν αὐτῇ τῇ ὥρᾳ) what they ought to say (ἃ δεῖ εἰπεῖ). Equivalent passages to this can be found in Matthew, chapter 10:20, and Mark chapter 13:11. Mark indicated that Jesus said that they were to say (τοῦτο λαλεῖτε) whatever would be given to them (ἀλλ’ ὃ ἐὰν δοθῇ ὑμῖν) at that hour (ἐν ἐκείνῃ τῇ ὥρᾳ). They would not be speaking (οὐ γὰρ ἐστε ὑμεῖς οἱ λαλοῦντες), but the Holy Spirit would be speaking (ἀλλὰ τὸ Πνεῦμα τὸ Ἅγιον) for them. Matthew indicated that Jesus said that it would be given to them (δοθήσεται γὰρ ὑμῖν) in that hour (ἐν ἐκείνῃ τῇ ὥρᾳ) what they should say (τί λαλήσητε). They would not be speaking (οὐ γὰρ ὑμεῖς ἐστε οἱ λαλοῦντες), but the Spirit of their Father would be speaking through them (ἀλλὰ τὸ Πνεῦμα τοῦ Πατρὸς ὑμῶν τὸ λαλοῦν ἐν ὑμῖν). In other words, the Holy Spirit, the Spirit of the Father, would speak for them and through them, so that they did not have to worry or prepare anything beforehand. Luke had the Holy Spirit teaching them, while Mark and Matthew had the Holy Spirit speaking for them. What do you know about the Holy Spirit?
