“When they hand you over,
Do not worry
About how you are to speak
Or what you are to say.
What you are to say
Will be given to you
At that time.
It is not you
Who speaks,
But the Spirit
Of your Father
Speaking through you.”
ὅταν δὲ παραδῶσιν ὑμᾶς, μὴ μεριμνήσητε πῶς ἢ τί λαλήσητε· δοθήσεται γὰρ ὑμῖν ἐν ἐκείνῃ τῇ ὥρᾳ τί λαλήσητε·
οὐ γὰρ ὑμεῖς ἐστε οἱ λαλοῦντες ἀλλὰ τὸ Πνεῦμα τοῦ Πατρὸς ὑμῶν τὸ λαλοῦν ἐν ὑμῖν.
Equivalent passages to this can be found in Mark, chapter 13:11, and Luke, chapter 12:11. Jesus told his disciples not to worry or be anxious (μὴ μεριμνήσητε), when they were handed over (ὅταν δὲ παραδῶσιν ὑμᾶς) to these courts or tribunals. They should not worry about how or what they should say (πῶς ἢ τί λαλήσητε). It will be given to them (δοθήσεται γὰρ ὑμῖν) in that hour at that time (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.
